What happens when a coil is rotated between two magnets?
The coil will produce an alternating electric current.
What happens if a coil is rotated between two magnets?
The coil will produce an alternating electric current.
Why is there an induced current in a coil when a coil is rotated between two magnets?
One of the laws of physics is that when a conductor moves in a magnetic field a current is induced in that conductor. If you then coil that conductor you effectively end up with several conductors and you'll get more current. Incidentally, you might be better of rotating the coil between the poles of a single magnet (a horseshoe type) rather than between two magnets as you've said in your question, because the two may cancel their magnetic fields out, depending on how they are positioned, whereas one won't.AnswerIt's voltage, NOT current, that is induced into a conductor. Current , resulting from this induced voltage, will only flow providing the conductor forms a complete circuit.
How are magnets used in generators?
There are two types of generators. First is Alternative current generator and second is Direct current generator. In both types of generators horseshoe-type magnets are used. This magnet is used so that when the shaft is rotated in anticlockwise direction the direction of force is upwards and the magnetic field lines are going from north to south or left to right. By using flemings right hand law the current wil flow from west to east. This magnet makes the current to flow in a circuit consistently to produce electricity.
How electricity is produced at power plants?
Huge generators turn magnets inside loops of wire. The resulting changes in the magnetic field relative to the coils induces an electrical current in the wire. The generators themselves are rotated by water- or steam- driven turbines.

What ia an altonator?
The correct word is Alternator. An alternator is an electric generator that produces alternating current. The generator's coil is rotated (by a turbine, motor, or other power source), and its circular path causes it to cut cross a magnetic field (set up by strong magnets), first in one direction, then the other, with each cycle. The electric potential induced in the coil by this motion thus alternates between positive and negative once with each cycle, resulting in alternating current. This current keeps the battery charged in an automobile.
How do magnets help generator produce electricity?
Magnets would have magnetic flux around. As a coil linked with this magnetic flux is rotated such that the flux would change then an electro motive force is induced. This is the way in which generator functions.
Describe how a simple generator produces electric energy?
A copper wire coil is rotated at speed in a magnetic field, to cause electrons to move. This is the electric current. The stronger the magnets and/or thicker the copper coil, the more current is produced
What are the different ways to induce current in a coil?
Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.

Who invented the generator using the principle that magnets can be used to produce an electri current?
The first dynamo based on Faraday's principles was built in 1832 by Hippolyte Pixii, a French instrument maker. It used a permanent magnet which was rotated by a crank. *wiki
