1
Induced when the magnetic field in the coil is changed by pushing a bar magnet into or out of the coil.
Electromagnetic Induction
New cards
2
The induced emf in a closed loop equals the negative of the time rate of change of magnetic flux through the loop.
Faraday's Law
New cards
3
The direction of any magnetic induction effect is such as to oppose the cause of the effect.
Lenz's Law
New cards
4
The voltage generated when the magnetic flux changes within a coil.
Induced Electromotive Force (emf)
New cards
5
The total magnetic field that passes through a given area.
Magnetic Flux (Φ)

6
Alternating current, the flow of electric charge that periodically reverses direction.
AC Current
New cards
7
Direct current, the flow of electric charge that flows in one direction.
DC Current
New cards
8
The process of calculating the magnitude of the induced emf based on changing magnetic field.
Induced emf Calculation
New cards
9
Materials like iron that can be magnetized and that have high magnetic permeability.
