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.
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.
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.
Why does the coil rotates when it is placed in between two magnet?
the coil between 2 magnets experience a force just like the ones in which a magnet is freely suspeneded and attracted by another manget. Secondly u apply current to it so electricity is converted to magnetic energy and the to kinetic energy (movement of the coil) -dumb student class 10 igcse
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

How alternating voltage is generated in a coil of wire when it is rotated between the poles of a magnet?
Electical current.=============================Answer #2:When a coil moves in the vicinity of a magnet, a voltage between the endsof the coil is produced. If the coil happens to be part of a closed circuit, thenthere could be an electrical current.Answer #3When a coil moves through a changing magnetic field, a voltage is produced, and when a resistor is connected to the coil some current flows and power is produced in the resistor. This power comes from the mechanical power needed to push the coil through the magnetic field when it carries a current.
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.
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.
Do magnets make electricity?
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
Is there a difference between magnets and electromagnets?
"electro magnets" are magnetic ONLY when electricity travels through a coil of wire surrounding them. "Magnets", as you state it, are permanent magnets and remain so independent of and not dependent upon any additional electrical charge.
What are the differences between electromagnets and permanent magnets, and how do electromagnets differ from permanent magnets?
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
What are the differences between electromagnets and permanent magnets, and how do they function differently?
Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets that retain their magnetism without an external power source. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
