Question 52

A teacher sets up three demonstrations, A, B, and C, to investigate electromagnetic induction.

  • Demonstration A: A bar magnet is pulled quickly away from a stationary coil.
  • Demonstration B: A primary coil connected to an alternating current (a.c.) supply transfers magnetic flux through an iron rod to a secondary coil connected to a voltmeter.
  • Demonstration C: A copper rod in a horizontal magnetic field is moved horizontally, parallel to the magnetic field lines.

Which of these demonstrations will produce a non-zero reading on the voltmeter?

A

A and B only

B

A and C only

C

B and C only

D
