What is a machine called that changes energy of motion into electrical energy?
A Dynamo (direct current) or Alternator (alternating current).The word Generator is occasionally also used, generically.
What uses a magnetic field to turn motion to electricity?
A microphone is a good example of a device that utilizes electromagnetic induction (Faraday's Law) to convert motion (vibrations in air) into electricity. The sound vibrates a membrane attached to a little magnet inside a coil of wire. The changing magnetic field induces a current in the wire.
What kind of device turns motion energy into electricity?
A generator.
What transfers motion the generator in wind energy?
hairy sacks

What uses motion to produce an electric current?
Any electrical generator except solar.
How is alternating current produced in a generator?
In an AC generator an armature is rotated in a magnetic field. This induces an electric current in the armature. if you want more look on the bottom. As the crank turns the armature rotates in the magnetic field. One side of the armature moves up, and the other side moves down. The up and down motion induces a current in the wire. The current is in opposite directions on two sides of the armature. After the armature turns halfway, each side of it reverses direction in the magnetic field. The side that moved up moves down, vice versa. The current is induced. As the Armature turns, slip rings turn with it. They are attached to the ends of the armature. As they turn, they make contact with the brushes. The brushes can be connected to the rest of the circuit. In this way, a generator becomes energy source.
What is a machine that uses an energy source to produce electricity?
A generator generates electricity. A simple generator consists of a magnetic field, relative motion between the conductor and magnetic field, and a conductor to carry electrical current to the load. Turbines drive the generators to create the necessary relative motion utilizing steam or water as the prime mover.
A generator can transforms into?
Generator can transform mechanical energy into electrical energy by converting the rotational motion of its turbine into electrical current through electromagnetic induction.
Explain how the induction motor gets loaded when the DC generator is loaded?
when the dc generator is loaded current will be drawn from it, therefore a back emf Will be generated, which opposes the motion of a generator, and hence, that opposition loads the three phase generator
What are 5 differences between motors and generators?
- Electric motor: Electrical → Mechanical - Electric Generator: Mechanical → Electrical A motor and generator perform opposite functions, but their fundamental structure is the same. Their structure is a coil mounted on an axel within a magnetic field. The motor is used to produce rotational motion from an electrical supply. In a motor an electric current is passed through the coil which forces it to rotate as the coil's magnetic field interacts with the field it is mounted in. The generator is used to produce an electric current from rotational motion (on large scale power stations a turbine is used to provide this rotation). In a generator the rotation causes the coil to rotate inside the magnetic field. This induces a current in the coil. The output current is alternating. In power stations it is usually the magnet which is attached to the axel and rotated, with the coils surrounding the magnet. However the end result is the same.
Can we transform rotational and translational motion into electric current?
Yes, Electricity we use is actually generated by transformation of energy from translation and rotational motion. Turbines are used to transform translational motion of water or water vapors into rotational motion, that is then transferred to the generator, where the magnets are used to generate Alternating current.
What is a device that changes motion into electricity using magnets and spinning coils of wire?
That would be an electric generator. They are also called dynamos. An alternator is a type of generator that makes alternating current.

How motion energy is converted into electrical energy in a generator?
Faraday showed hiow to do this in his Law: dB/dt = - DelxEv. A generator creates a changing magnet field and this induces an electric field in a circuit coupled to the changing magnetic.field. Hydroelectric plants use falling water to create the changing mag field.
How is a motor different from a generator and how is a generator different then a mot or?
A motor takes electricity and creates rotating motion. A generator takes rotating motion and turns it into electricity.
