A student is constructing a simple a.c. generator. To increase the maximum (peak) electromotive force (e.m.f.) induced in the coil, three suggestions are made:

  1. Rotate the coil at a higher speed.
  2. Use a stronger permanent magnet to provide a denser magnetic field.
  3. Increase the number of turns of wire on the coil.

Which suggestions will help to increase the peak e.m.f.?

A

1, 2 and 3

B

1 and 2 only

C

1 and 3 only

D
