What uses a magnet to change mechanical energy into electrical energy?

It's called a generator. Most of them spin a magnet within a coil of wire, which induces a voltage in the coil.
The size ranges from something that you can hold in your hand to big multi-ton giants that are used in power plants.
Every automobile has a generator in it. These are usually referred to as "alternators," since they produce alternating current, but the principle is the same.

Can you make energy using a magnet?
There is really no way to make energy - do some reading about the Law of Conservation of Energy for more details. With a magnet, you can convert one type of energy into another - mechanical energy into electrical energy, or electrical energy into mechanical energy.
Describe the energy transformation that takes place in a generator?
Mechanical energy to electrical energy. A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical). Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.
Which pair is made up of two things that work in opposite way's A bar magnet and horseshoe magnet B chemical energy and mechanical energy C generator and motor D solar energy and geothermal energy?
C. Generator and motor. In case of generator mechanical energy is converted into electrical energy But in motor, electrical energy is changed into mechanical energy.
What are 2 things of energy that generators convert into electrical energy?
Heaters (With Resistive Coils) will change Electrical Energy into Heat Energy. Electric Motors (AC and DC) will convert Electrical Energy into Motion Energy.
How do mechanical energy becomes electrical energy?
Through a generator I.e. turn the generator which turns the coil around a magnet which in turn creates an electrical current.

How do you transfer 40kph mechanicall energy into electrical energy?
The usual method to convert mechanical energy into electrical energy is to move a wire in a magnetic field (or alternately, move the magnet near to a wire).
What is masdar city?
Magnet wire plays a critical role in three areas of energy transformation: electrical to electrical, electrical to mechanical, and mechanical to electrical. Electrical to electrical transformation involves transformers, which are used to transfer power. Transformers are used for power generation by utility companies, for power voltage conversion, and in electrical controls in industrial and home uses. Electrical to mechanical transfer is necessary for motorized appliances, automobiles, industrial machinery, and residential and commercial HVAC systems. Magnet wire is a key component in each of these applications. Mechanical to electrical transformation occurs when machine power is converted into electricity. This type of transformation includes generators, which turn mechanical power into electrical energy through the use of magnet wire.
Mechanical energy to electrical energy?
mechanical energy is turned into electrical energy using a generator. a generator works by spinning a coil in between the north and south poles of a magnet. this creates a electric current.
Which change occurs in an electric motor?
Electrical energy is used to create a electromagnet with alternating poles. These alternating poles will cause another magnet with constant poles attached to an armature to turn and create mechanical energy.
What energy changes in a telephone?
The voice from a person's mouth (air flow) vibrates a diaphram which translates the vibrations (mechanical energy) into electrical wave oscillations using an magnet and a coil. These electrical oscillations are superimposed on to a high frequency carrier wave and sent over physical wires, under sea cables, micro wave towers, satellites etc (purely electrical energy) and at the receiving end the carrier wave is removed and only the wave that was generated by the voice and hence the diaphram and hence the magnet and the coil is made to drive a coil over which is a diaphram which vibrates (mechanical energy) to reproduce the sound. Of late digital phones have come into the market but the basic principle is the same. Convert mechanical energy to electrical energy and then convert electrical energy to mechanical energy.
What do magnet have to do with simple motors?
Motors convert electrical energy to mechanical energy through moving electric conductors through a magnetic field. Magnets can be permanent magnets or electromagnets.
