Fleming's Hand Rules & the Grip Rule Simulation

Magnetic forces act at right angles to both the field and the current, which is why a flat textbook diagram is hard to read. This 3D simulation places a hand along the real vectors, computed from the cross product, so you can turn the scene and see the rule from any side. Fleming's left-hand rule (for motors): first finger along the field, second finger along the current, and the thumb gives the force.

Fleming's right-hand rule (for generators) uses the same fingers for field and motion of the conductor to give the direction of the induced current. The right-hand grip rule gives the circular field round a wire: thumb along the current, fingers curl the way the field lines go. Pathik Sir asked for all three in one place — reverse any direction and watch the hand follow.
