1

New cards

Magnetic flux linkage

The product of the number of turns on the coil and the flux through the coil (NФ)

2

New cards

Faraday’s law of electromagnetic induction

The emf induced is directly proportional to the rate of change of magnetic flux (flux linkage)

3

New cards

Lenz’s law

The induced current flows in a direction so as to set up a magnetic field to oppose the change in magnetic flux

4

New cards

Diode

A component that only allows current to flow in one direction
