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.
Answer
It'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.

What happens when a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction and is the basic principle behind generators and electric motors. The amount of current induced depends on the speed of rotation and the strength of the magnetic field.
What happens if a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction. The induced current produces an electromagnetic force, creating a torque that causes the coil to rotate. This is the principle behind electric generators.
Why there is an induced current in a coil when a coil is rotated between two magnets?
When a coil is rotated between two magnets, the magnetic field lines cut across the coil, inducing an electromotive force (EMF) according to Faraday's Law of electromagnetic induction. This EMF creates an induced current in the coil as the electrons inside the coil are pushed in a direction that opposes the change in magnetic field, following Lenz's Law.
What is the formula to calculate the average induced emf in a coil when it is rotated in a magnetic field?
The formula to calculate the average induced emf in a coil when it is rotated in a magnetic field is given by: Average Induced EMF N B A sin() Where: N number of turns in the coil B magnetic field strength A area of the coil angular velocity of rotation angle between the magnetic field and the normal to the coil
What produces an electric current when a coil of wire is wrapped around an iron core is rotated near a magnet?
This phenomenon is known as electromagnetic induction. When the coil of wire is rotated near a magnet, the changing magnetic field induces an electric current in the wire due to Faraday's law of electromagnetic induction. The iron core enhances the magnetic field, resulting in a stronger induced current.

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.

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.

Which device contains coils of wire that are stationary and rotating magnets that are rotated by turbines?
The device you are referring to is a generator. In a generator, stationary coils of wire are situated within a rotating magnetic field created by magnets, which are often attached to turbines. As the turbines spin, they cause the magnets to rotate, inducing an electrical current in the stationary coils through electromagnetic induction. This process converts mechanical energy into electrical energy.
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
Where do you use magnet to generate energy?
Magnets are used in generators to convert mechanical energy into electrical energy. When a magnet moves near a coil of wire, it induces an electric current in the wire through electromagnetic induction. This current can then be harnessed as electricity for various applications.
