electromagnetic induction

Question 1

magnetic flux density (B)

Answer 1

• a representation of the magnitude and direction of the magnetic field

Question 2

magnetic flux linkage (N0/)

Answer 2

• the product of the number of turns of the coil and the flux through the coil

Question 3

Faraday’s law of electromagnetic induction

Answer 3

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

Question 4

Lenz’s law

Answer 4

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

Question 5

diode

Answer 5

• a component that only allows current to flow in one direction
