Changing Magnetic Fields
A stationary magnetic field has no effect on a wire or current-loop,
However, . . . .
A moving or changing magnetic field does produce a current in a current loop or a voltage across the ends of a current loop. This is called electromagnetic induction and the current or voltage is called an induced current or an induced voltage.
