Electrodynamics Flashcards
1
Q
Define magnetic flux linkage
A
the product of the number of turns on the coil and the flux through the coil
2
Q
State Faraday’s law of electromagnetic induction
A
the emf induced is directly proportional to the rate of change of magnetic flux (flux linkage)
3
Q
State Lenz’s law
A
the induced current flows in a direction so as to set up a magnetic field to oppose the change in magnetic flux
4
Q
Define a diode
A
a component that only allows current to flow in one direction
