An electric generator transforms mechanical energy into electrical energy. this process could be done by which of these? a) using wind to spin a magnet around. b) connecting a battery to a coil of wire. c) turning a wheel that contains electrons. d) spinning a coil of wire near a large magnet.

its d

Explanation:

D) Spinning a coil of wire near a large magnet.

Explanation:

From Faraday's law of induction, when a conducting coil of wire is placed in changing magnetic flux, an emf is induced which produces current in the coil.

Induced emf is given by:

A generator is based on the same principle.

The mechanical energy of rotating coil is converted to electrical energy when current is induced. Thus, the correct option is D) Spinning a coil of wire near a large magnet.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
