2.2 Electromagnetism

Question 1

What happens to the voltage when a coil wire is moved within a magnetic field?

Answer 1

There is induced voltage when the wire moves up and down between the poles.

Question 2

What factors affect the size of an induced voltage when a wire is moved within a magnetic field?

Answer 2

Moving the wire faster between the poles of the magnet
Using a stronger magnet
Use more conductor eg. make a few turns of the conductor.
