Larmor precession

This animation shows Larmor precession for a spin 1/2 in a magnetic field.

You can change the direction of the magnetic field by dragging the green arrow while holding down the Shift key.
As in the previous simulation, you can also change the spin state by dragging the yellow arrow with the mouse, the Ctrl key being pushed down. You can also change the frame orientation by dragging the bounding sphere with the mouse.
