GEN-PHYSICS-2-WEEK-1-MAGNETIC-INDUCTION

Induced when the magnetic field in the coil is changed by pushing a bar magnet into or out of the coil.

Electromagnetic Induction

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

The direction of any magnetic induction effect is such as to oppose the cause of the effect.

Lenz's Law

The voltage generated when the magnetic flux changes within a coil.

Induced Electromotive Force (emf)

The total magnetic field that passes through a given area.

Magnetic Flux (Φ)

Alternating current, the flow of electric charge that periodically reverses direction.

AC Current

Direct current, the flow of electric charge that flows in one direction.

DC Current

The process of calculating the magnitude of the induced emf based on changing magnetic field.

Induced emf Calculation

Materials like iron that can be magnetized and that have high magnetic permeability.

Ferromagnetic Material

The process by which a diode starts to conduct in reverse after a certain voltage threshold is reached, often used in spark plugs.
