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.
Vincent Hilpert
A device that uses a magnetic field to turn motion into electricity is called a generator or an alternator. These devices typically use a rotating magnet, also known as a rotor, within a stationary coil of wire, also known as a stator, to produce an electric current through electromagnetic induction. As the magnet rotates, it creates a changing magnetic field that induces a voltage in the coil, generating electricity.

What uses a magnetic field to turn motion into 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.
How does electricity produce motion?
In an electric motor electricity is used to create a moving magnetic field which forces the shaft of the motor turn. For more details see the 'how stuff works' web site for electric motors.
How is a motor used in the generation of electricity?
Motors turn rotors that rotate coils of wires over a magnetic field, which creates an electric current in the wire.
What would be used to make a simple electromagnet?
Some material whose spins can be aligned (and in turn align spins of other materials close enough to feel the effects of its magnetic field) and electricity.
How does coiling a wire affect the magnetic field generated an electromagnet?
Coiling a wire increases the magnetic field of an electromagnet because the magnetic field around a wire is circular and perpendicular to the wire. Each turn of the wire reinforces the field of the one next to it. The magnet field is strengthened. (I was in A+, too ;) ) - Dawn Ayers
What is the purpose of a generator in terms of energy?
It uses magnetic field to turn motion into electricity
What is the primary purpose of a generator in terms of energy?
It uses magnetic field to turn motion into electricity

How do electric generators produce a current?
they produce a current the magnetic field has to turn motion into that current. the gas coal or water pass on that current to the magnetic field.
How do you make lectricidy?
Electricity can be generated by moving a wire relative to a magnetic field. This induces a voltage in the wire (due to interaction of magnetic fields) which in turn induces a current if the wire is in a complete circuit. This current is the movement of electrons, also known as electricity.
How is electricity used to move a car?
Electricity can create magnetic fields. A magnetic field will attract or repel another magnetic field. That principle is used in the manufacture of electric motors. Magnetic fields are created in both an armature and an outside winding. When the magnetic fields are opposite, the armature tries to turn so that it is in line with the outside winding. Then the magnetic field changes polarity and the armature continues in the same direction, pushing the magnetic fields away. The process continues, repeatedly and quite rapidly to make an electric motor armature turn. The armature can be connected to a drive shaft or even directly to a wheel to make the vehicle move.
How is a motor used in the generation of electricity?
Motors turn rotors that rotate coils of wires over a magnetic field, which creates an electric current in the wire.
What kind of field is electricity?
Electrostatic field surrounds a stationary charge. A moving charge has magnetic and electric field surrounding it. But since the mag. field at a point due to the moving charge keeps changing, there is also an induced electric field. this ind. electric field in turn induces a magnetic field. and this goes on in a cycle. (Maxwell equation)
What device uses a magnetict field to turn motion into electricity?
That is a generator. For large scale generation of electricity the motion is provided either by falling water, like in the Hoover Dam or at Niagara Falls, or by steam-driven turbines.
Why is an electromagnet not a permanet magnet?
because the copper wire in it is only magnetic when there is electricity running through it so when you turn of the electricity soure it is no longer magnetic
How a electorical motor works?
A current of electricity flows through some conductors inside the motor. These conductors create a magnetic field which in turn moves the magnet connected to the rotor.
