Electromagnetic Induction
Ways to create motion between lines of force:
1. Move the Conductor through a stationary, unchanging strength magnetic field.
2. Move magnetic lines of force through a stationary conductor with an
unchanging strength magnetic field.
3. Vary the magnetic flux strength from a stationary magnet through a stationary
conductor.
To regulate the strength of the induced current
1. the strength of the magnetic field.
2. the speed of the motion between lines of force and the conductor.
3. the angle between the magnetic lines of force and the conductor.
4. the number of turns in the conducting coil.
Lenz's Law: The current induced in a circuit due to a change in the magnetic
field is so directed as to oppose the flux, or to exert a mechanical force to oppose
the motion.

Mutual Induction: The result of two coils being placed in close proximity with
a varying current supplied to the first coil, which then induces a similar flow in
the second coil.
Primary Coil: The coil supplied with the current first.
Secondary Coil: The coil in which the current is induced.
