I have a physAn e. m.f. is induced across a wire when it moves through the magnetic field between the poles of a magnet. Which electrical device operates because of this effect?ics exam someone please help 9th grade &

Generator.

Explanation:

In a generator, an e.m.f. is induced across a wire when it moves through the magnetic field between the poles of a magnet.

The mode of operation of a generator is that a metal core with copper tightly wound to it (conductor coil) rotates rapidly between the two (2) poles of a horseshoe magnet type. Thus when the conductor coil rotates rapidly, it cuts the magnetic field existing between the poles of the horseshoe magnet and then induces the flow of current.
