Magnetism- physics

Set the number of wire loops to three, the bar-magnet strength to about 50 percent, and the loop area to 100 percent. Note the maximum voltage on the voltmeter. Assuming that one major division on the voltmeter is 5V, what is the maximum voltage when using only a single wire loop instead of three wire loops?

  1. 5 V
  2. 15 V
  3. 125 V
  4. 53 V

I think its 15V, can someone please verify.
