Name a device that is designed to change electrical energy into kinetic energy?

Answer 1

A Generator
AC and DC generators(also called dynamos).

Whenever magnetic flux through a closed wire loop changes current flows in it. We use mechanical energy to produce change in flux and generate electricity.
A device that converts mechanical energy into electrical energy is called an Electric Generator. It works by inducing an electric current in a loop of wire by using magnetic fields.
An electrical generator or Dynamo. The mechanical energy moves a magnetic field relative to electric coils and creates electricity. Little Dynamos on bicycles provide light at night.

Answer 2

A generator in a power plant converts rotating kinetic energy into electrical energy An electric motor is a device which changes electrical energy into kinetic. For example-- Fans could be like electric energy to kinetic energy...

Answer 3

A generator in a power plant converts rotating kinetic energy into electrical energy. So it is a generator

In order for Kinetic energy to be converted into electrical energy, the kinetic energy usually drives the rotation or oscillation of a magnet in close proximity to coiled wire.

A bar magnet can be moved up and down through the centre of a looped coil of wires. As the wire comes into contact with the magnetic field of the magnet, a current is induced in the wire. (see Left hand rule)

Likewise, a collection of magnets attached to a large prop shaft when rotated will induce a current in a large array of coiled wires which surround but do not touch the circled array of magnets.

Kinetic energy is essentially converted into electrical energy in most production of electricity. Oil, Gas, Coal or Nuclear energy are all used to heat water; the steam of which turns turbines and therefore the prop shaft. (Chemical energy-kinetic energy-electrical energy)

Through a generator shaft........

I imagine the questioner knows that, but wants to what is on the shaft!

An electrical generator is a set of coils of wire so arranged than when rotated they cut across a strong magnetic field, and it is this that induces the current in the windings, extracted by suitable means for feeding it tothe circuit connected to the machine's output.

A generator does this by passing a rotating coil of wire through a magnetic field. Electric current is induced in the coil.

Answer 5

An electric motor turns electrical energy into motion.
An Electric motor commonly referred to as AC motor which utilize the induced magnetic field created by inductors which converts it into rotational energy

Answer 6

A starter motor, such as found on a motor vehicle.

Answer 7

Generators and Alternators convert Kinetic Energy into Electrical Energy. So do Microphones, which are devices called Transducers.

Answer 8

An electric motor.

Answer 9

Dynamo
