Question 4

An engineer tests a coil for a portable generator. The coil is moved through the magnetic field of a fixed magnet and the potential difference induced across the coil is measured.

Which change would increase the size of the induced potential difference?

[1]
A

Moving the coil through the field at twice the speed

B

Holding the coil still in a magnetic field twice as strong

C

Moving the coil through the field in the opposite direction

D

Moving the coil at the same speed for twice as long
