  Building on a new model proposed recently for calculating constant electro-magnetic field values, the present article explores the electro-magnetic field configuration generated by parallel electrical wires. This imposes a reevaluation of the drawing procedure for constructing field curves with a constant field values around multiple parallel electrical conducting wires. To achieve this, we employ methods akin to those used for creating contours on topographical maps, ensuring a consistent numerical field value along the entire length of the field curves. Subsequent calculations will be conducted for scenarios where wires are not parallel.

Introduction</title><p>In 1820, Oersted made observations that an electrical current flowing through a lengthy wire generates magnetic field vectors in its vicinity [<xref ref-type="bibr" rid="scirp.130409-ref1">1</xref>] . He defined this vector to be oriented perpendicular to the wire and contingent upon the electrical current. This vector has the capability to reorient small compasses and align iron filings [<xref ref-type="bibr" rid="scirp.130409-ref2">2</xref>] . Then, successive vectors can be drawn, forming curves traditionally referred to as magnetic field lines or magnetic flux lines [<xref ref-type="bibr" rid="scirp.130409-ref3">3</xref>] . These experimental lines resemble circles around an individual straight electrical wire, as reported by M. Zollner in 2002 [<xref ref-type="bibr" rid="scirp.130409-ref4">4</xref>] . Around this straight wire and employing the Biot-Savart law [<xref ref-type="bibr" rid="scirp.130409-ref5">5</xref>] , these circles have been mathematically calculated [<xref ref-type="bibr" rid="scirp.130409-ref6">6</xref>] . In another scenario, such as when using a circular electrical wire, this vector can be observed by employing iron filings [<xref ref-type="bibr" rid="scirp.130409-ref7">7</xref>] . It is feasible to compute this vector along the entire perpendicular axis of this current loop [<xref ref-type="bibr" rid="scirp.130409-ref6">6</xref>] . Along this axis, non-zero vectors have been computed [<xref ref-type="bibr" rid="scirp.130409-ref6">6</xref>] , with their values diminishing to zero as they move further away from the circular wire. Since the first observation, no other concept has been developed to calculated magnetic field lines around electrical wires.</p><p>In our most recent publication regarding the field generated by an infinite electrical wire, we have introduced a new alternative definition for the field at a specific location in proximity to the wire [<xref ref-type="bibr" rid="scirp.130409-ref8">8</xref>] . We had suggested associating a single point with one physical field value and three vectors. In the present paper, we want to test this recently proposed model. To do so we will focus solely on the field value, without considering these three vectors. This consideration will reduce the number of parameters employed. As previously evaluating the magnitude of this field value, it will be directly proportional to the current in the wire and inversely proportional to the distance from it. This vector less definition will be employed throughout this article to determine the positions of points that share the same value generated by parallel electrical wires.</p><p>The employed method in this paper, is founded on the widely recognized process of constructing topographic contour maps, which comprises individual data points [<xref ref-type="bibr" rid="scirp.130409-ref9">9</xref>] [<xref ref-type="bibr" rid="scirp.130409-ref10">10</xref>] . In this topographic process, each point’s value is assessed based on its elevation or depth and then positioned within horizontal planes [<xref ref-type="bibr" rid="scirp.130409-ref11">11</xref>] . Using this approach, field points sharing the same field value will be situated within a plane that is perpendicular to the wires.</p><p>In this paper, we depict points surrounding straight electrical-current wires with varying field values in several scenarios, including cases with different wire quantities: a single electrical-current wire, two wires with identical intensity and direction, parallel wires with opposing electrical-current directions, two parallel wires with different current intensities, scenarios requiring level assessment, and finally, instances involving at least five identical wires aligned in the same current direction. During the discussion, we elaborate on the validity of the superposition principle within our test of constant field values.</p><p>Units, used in this paper, are meters (m) for distances, Amperes (A) for electrical-current in wires, and Ampere/meter (A/m) for field values at a point placed everywhere out of the wires. To do so, the value of the vacuum permittivity is chosen equal to one.</p><p>In summary, this paper does not utilize classical magnetic field lines based on magnetic vectors. Instead, it employs as defined in our model previously published [<xref ref-type="bibr" rid="scirp.130409-ref8">8</xref>] of field values derived from physical calculations, enabling the construction of curves comprised of sequences of points.</p></sec><sec id="s2"><title>2. Theoretical Bases for the First Application of Our Previously Published Model</title><p>This chapter uses a field definition with physical values as calculated in our previous article [<xref ref-type="bibr" rid="scirp.130409-ref8">8</xref>] knowing that this field definition has not been found in other scientific publications. The main point was to introduce specific field values (not a vector) proportional to electrical current in wires and inversely to its distance.</p><p>The physical field value at any point on a perpendicular surface surrounding a solitary electrical wire can be assessed [<xref ref-type="bibr" rid="scirp.130409-ref6">6</xref>] . This value corresponds to I/r, where I represent the electrical current and r is the distance from the wire. In the case of three conducting wires, a single point “p” located within a plane perpendicular to the three wires derives its field value through the summation of these values, as depicted in <xref ref-type="fig" rid="fig1">Figure 1</xref>.</p><p>In <xref ref-type="fig" rid="fig1">Figure 1</xref>(a) (left), when an electrical current flows downward, it imposes a positive field value of I/r with I &gt; 0. In <xref ref-type="fig" rid="fig1">Figure 1</xref>(a) (left), when the electrical current is flowing upward, the field value becomes negative, denoted as I/r with I &lt; 0. By superimposing all these field values at point “p,” the result is equivalent to the summation of the three computed values, resulting in ∑ I/r, as illustrated in <xref ref-type="fig" rid="fig1">Figure 1</xref>(b) (right). For the author, this holds significant physical significance as it imbues our model with a robust additivity property at all points within the plane perpendicular to the wires.</p><p>Note: The additivity of these values contradicts the conventional additivity of magnetic vectors.</p></sec><sec id="s3"><title>3. Application</title><p>To generate a curve on the plane surface perpendicular to the wires, it is necessary for all points to share the same field value. (This type of curve does not resemble a traditional magnetic field line.) We will demonstrate that our drawing method bears a strong resemblance to creating contour lines on conventional topographic maps, where point values correspond to their elevation or depth [<xref ref-type="bibr" rid="scirp.130409-ref9">9</xref>] .</p><sec id="s3_1"><title>3.1. One Electrical-Current Wire</title><p>Traditional magnetic field lines assume a circular shape when generated by a single conducting wire [<xref ref-type="bibr" rid="scirp.130409-ref2">2</xref>] . These lines are determined using magnetic vectors equivalent to I/r. In <xref ref-type="fig" rid="fig2">Figure 2</xref>, our field value coincides with the magnetic vector because only one electrical wire is present. Each circular curve possesses a distinct “field value,” which diminishes as the distance from the wire increases. In certain cases, field values may eventually reach zero as the distance approaches infinity.</p><p>To highlight the resemblance between the field curves and topographic maps, one could draw a parallel between a field value of zero (A/m) and sea level on a topographic map. In <xref ref-type="fig" rid="fig2">Figure 2</xref>(c), a 3D representation illustrates this concept, where like in topographic maps, field curves cannot intersect with lines representing different levels [<xref ref-type="bibr" rid="scirp.130409-ref12">12</xref>] . The 3D rendering of curve values always maintains a planar arrangement, akin to the contour lines on a topographic map illustrating the relief contour [<xref ref-type="bibr" rid="scirp.130409-ref12">12</xref>] .</p></sec><sec id="s3_2"><title>3.2. Two Electrical-Current Wires</title><p>In this chapter, we employ two wires with identical electrical current intensities of one ampere (A) and the same direction. At any point on the planar surface, the field value is the result of combining two distinct I/r values. While field curves are not depicted with vectors, it’s worth noting that conventional magnetic field lines are not included; however, certain training courses may introduce such a classical calculation approach [<xref ref-type="bibr" rid="scirp.130409-ref13">13</xref>] .</p><p>In <xref ref-type="fig" rid="fig3">Figure 3</xref>, the field curves are depicted in various colors to represent distinct physical values.

Discussion</title><sec id="s5_1"><title>5.1. Gauss’s Law of Magnetism</title><p>In Gauss’s law of magnetism, it is asserted that magnetic field lines neither have a distinct starting point nor an endpoint; they extend infinitely [<xref ref-type="bibr" rid="scirp.130409-ref15">15</xref>] . Every 3D illustration in this current article adheres to this principle. These field lines are nearly circular, with only one extending to infinity, as seen in <xref ref-type="fig" rid="fig4">Figure 4</xref>.</p><p>In our model, each curve maintains a uniform field value throughout its length. Therefore, when certain positions of the curves are at an infinite distance from the wires, all positions must exhibit a field value of zero (A/m).</p><p>This characteristic, exemplified by the linear black curve in <xref ref-type="fig" rid="fig4">Figure 4</xref>, represents an enhancement of Gauss’s law by introducing the concept of zero field value in straight lines.</p></sec><sec id="s5_2"><title>5.2. Circle Field Curves</title><p>M. Zollner conducted experiments involving magnetic fields with two parallel current wires. When the currents were in opposite directions, he represented the field lines as eccentric circles [<xref ref-type="bibr" rid="scirp.130409-ref4">4</xref>] . In <xref ref-type="fig" rid="fig4">Figure 4</xref> of this article, the field lines may indeed resemble circles when they are near one of the current wires. However, as the field values approach zero, the lines progressively adopt a more linear configuration around the midpoint between the two conducting wires. Through this comparison, it becomes evident that both theoretical and experimental lines are not significantly discrepant.</p><p>One notable advantage of the theory proposed in this article is its applicability to highly intricate electrical scenarios, offering a valuable tool for analyzing complex electrical configurations.</p></sec><sec id="s5_3"><title>5.3. Superposition Principle for Field Curves</title><p>Regarding magnetic field lines, Feynman remarked that “The field lines, however, are only a crude way of describing a field, and it is very difficult to give the correct, quantitative laws directly in terms of field lines”. He also noted that “the ideas of the field lines do not contain the deepest principle of electrodynamics, which is the superposition principle”, Furthermore, he pointed out that “we don’t get any idea about what the field line patterns will look like when both sets are present together” [<xref ref-type="bibr" rid="scirp.130409-ref16">16</xref>] .</p><p>In our paper, we introduce a novel paradigm for field values, employing a distinct theoretical approach to construct curves based on electrical current fields. In <xref ref-type="fig" rid="fig1">Figure 1</xref>(b), the addition of field values (without vectors) enables the representation of highly intricate structures. As a result, it appears that our article adheres to the superposition principle, as complex field configurations can be effectively delineated using this approach.</p><p>At this juncture in the article, the reader might find that a clear and comprehensible presentation has been provided, substantiating the author’s claims effectively.</p></sec></sec><sec id="s6"><title>6. Conclusion</title><p>This article does not use the conventional magnetic field vectors to represent field curves and instead employs specific field values for each point surrounding electrical wires. The field value is locally equal to the ratio of current divided by distance (I/r). In the case of parallel wires, these points are arranged into planar curves, which can assume various forms that are easily calculated through a linear summation of the field values. These unique characteristics bear a resemblance to the level curves found in topographic maps. Thanks to this analogy, a current field curve can intersect itself through a pass, but only once for each conducting wire. Looking ahead there is potential for extending our previous model to encompass non-parallel wire configurations, which could present intriguing opportunities for further exploration. The main application of our proposed model will probably be a precise drawing of field lines in electrical motors.</p></sec><sec id="s7"><title>Conflicts of Interest</title><p>The author declares no conflicts of interest regarding the publication of this paper.</p></sec><sec id="s8"><title>Cite this paper</title><p>Auvert, G.
