When a magnet is plunged in and out of a coil of wire, voltage is induced in the coil
Chapter 0, Problem 2(choose chapter or problem)
When a magnet is plunged in and out of a coil of wire, voltage is induced in the coil. If the rate of the in-and-out motion of the magnet is doubled, the induced voltage [doubles] [halves] [remains the same]. If instead the number of loops in the coil is doubled, the induced voltage [doubles] [halves] [remains the same].
