  ABSTRACT: The nitrogen-vacancy center in diamond offers unique possibilities for room-temperature quantum magnetometry. Here, we demonstrate and explore diamond magnetometry with a portable, educational toolkit from Quantum Education Initiative (QEI). A green (532 nm) laser diode and optical elements are used to electronically excite NV− electrons, while a transverse magnetic field induces spin mixing. Through all-optical initialization and readout (fluorescence), we gained a conceptual understanding of diamond-based magnetometry. We aligned several optical elements and measured intensity data to create an intensity versus magnetic field relationship. The employed magnetometry scheme does not attain state of the art sensitivities, but it is purely employed for educational purposes.
