P6 ELECTROMAGNETISM

Question 1

Electromagnetic induction

Answer 1

is the production of an electromotive force (emf) across an electrical conductor

in a changing magnetic field.

Question 2

faraday’s law

Answer 2

states that the emf induced in a coil is directly proportional to the rate of

change of magnetic flux linkage.

Question 3

lenz’s law

Answer 3

states that induced current will flow in a direction so as to set up a magnetic

field to oppose the change in magnetic flux.
