spin-orbit coupling
... which exerts a force on the magnetic moments. • When the magnetic moment is parallel to B, it moves in the direction of increasing field strength, while an anti-parallel magnetic moment moves towards lower field strength. ...

Electromagnetic induction
... Important factors in inducing currents • 1. An emf is induced if the coil or the magnet (or both) move (change in flux). • 2. The size of the induced emf depends on the speed of movement. • 3. The induced emf depends on the strength of the B field. • 4. Changing the area inside the magnetic field • ...
