If a magnet is pushed into a coil, voltage is induced across the coil. If the same magnet is pushed into a coil with twice the number of loops,
A) the same voltage is induced.
B) twice as much voltage is induced.
C) four times as much voltage is induced.
D) one half as much voltage is induced.
E) none of these

Quizplus · Accepted Answer

Doubling the number of loops in a coil doubles the voltage induced when a magnet is pushed into it, due to the direct proportionality between the number of loops and the induced voltage according to Faraday's law of electromagnetic induction.

If a Magnet Is Pushed into a Coil, Voltage Is
