Electric current can best be induced in a wire by

a. stretching the wire.

b. moving a magnet up and down near the wire.

c. setting the wire near a magnet.

d. rotating the wire. E. none of the above

Electric current can best be induced in a wire by moving a magnet up and down near the wire is the correct answer.

Explanation:

Electric current is the flow of electron that carries the negative charge in the electric circuit.

Electric current induced in the wire through:

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

this would be about 43%
