Our setup consisted of a HeNe laser with a wavelength of 670 nm, a solenoid with a coil constant of XXX V/A, 11.1 mT/A,  a rotatable polarizer, and a photodiode. The current through the solenoid was controlled by a programmable bipolar operational power supply to produce either a DC current, AC current, or AC current with a DC offset. This allowed us to produce wither a constant magnetic field $B_0$ or a time varying magnetic field $B = B_0 + B_1 \cos(\omega t)$ as needed.
