Description: Electron Spin Resonance is simulated using a ball and Helmholtz coils. The ball contains magnet whose moment points long the black stem of the ball (see picture above). The gravitational field of the Earth acts as a constant magnetic field and the alternating field is produced by switching the direction of current in the coils.

Special Instructions: Remember to turn on the air pump.
