Moving a magnet inside a coil of wire will induce a voltage in the coil. How is the voltage in the coil increased?

by moving the magnet inside the coil of wire more slowly

by moving the magnet inside the coil of wire more rapidly

by holding the magnet absolutely still

by moving the coil of wire slowly, and keeping the magnet stationary

  1. Well, you could use Maxwell's equations, but it might be easier to make a common sense guess.
    If moving the magnet makes a voltage, then it is likely that moving it faster will make a bigger voltage.
