AC generationQuestion 162 of 1506

The field strength and the speed of a conductor are both doubled. What happens to the induced voltage?

  1. It becomes twice as large
  2. It becomes four times larger
  3. It stays the same
  4. It becomes eight times larger
Show answer

Correct answer: It becomes four times larger

Voltage is proportional to the field strength and to the speed, so 2 × 2 = 4.
