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
When a coil is placed between two magnets, it experiences a force known as the Lorentz force. This force is a result of the interaction between the magnetic field of the magnets and the electric current flowing through the coil. As a result, the coil rotates due to the torque generated by this force.

When is induced electromotive force produced in a coil placed near a magnet?
An induced electromotive force is produced in a coil placed near a magnet when there is a relative motion between the coil and the magnetic field. This motion causes a change in the magnetic flux passing through the coil, leading to the generation of an electromotive force according to Faraday's law of electromagnetic induction.
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
Can a round magnet produce electricity if it's rotating?
Yes, a round magnet rotating in a coil of wire can produce electricity through electromagnetic induction. As the magnet spins, it generates a changing magnetic field that induces a current in the coil according to Faraday's law of electromagnetic induction. This current can be harnessed as electrical energy.
What are the types of galvanometer?
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
Differences between Permanent magnet moving coil and moving iron?
Permanent magnet moving coil (PMMC) instruments use a moving coil that is suspended between the poles of a permanent magnet, whereas moving iron instruments use a stationary coil and a moving iron piece that moves within the coil's magnetic field. PMMC instruments are more accurate but have limited range, while moving iron instruments are less accurate but can measure higher currents. PMMC instruments are inherently more expensive compared to moving iron instruments.
When is induced electromotive force produced in a coil placed near a magnet?
An induced electromotive force is produced in a coil placed near a magnet when there is a relative motion between the coil and the magnetic field. This motion causes a change in the magnetic flux passing through the coil, leading to the generation of an electromotive force according to Faraday's law of electromagnetic induction.
Definition of PMMC instrument?
An ammeter or other electrical instrument in which a small coil of wire, supported on jeweled bearings between the poles of a permanent magnet, rotates when current is carried to it through spiral springs which also exert a restoring torque on the coil; the position of the coil is indicated by an attached pointer.
Generator consisting of a coil that rotates between the poles of an electromagnet?
dynamo
What happens if a direct current is put through a coil suspended between the poles of a magnet?
The coil will align itself with the magnetic field (poles) of the magnet.
What happens when a magnet is pushed into the coil during an experiment to demonstrate electromagnetic induction?
-- While the magnet is moving, there is a voltage between the ends of the coil and, if there's any connection between the ends, then there's a current in the coil. -- When the magnet stops moving, all of that goes away. -- When the magnet is pulled out, it all happens again, but with the opposite polarity.
When was Magnet's Coil created?
Magnet's Coil was created in 1995.
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
A moveable coil or wire found between the poles of a magnet in a generator?
The armature.
What is a Generator consisting of a coil that rotates between the electromagnet causing a current to flow in the armature?
dynamo
What is the role of a magnet in woofers?
The voice coil of a loudspeaker is placed in an annular space within the magnet assembly and is connected to the loudspeaker's paper cone. An audio signal creates a current in the coil and this generates a magnetic field around the coil which reacts with the permanent magnet of the woofer. The coil and cone move in and out like a piston in a car engine depending on the polarity of the audio signal. This is called the 'Motor effect' and is basically a linear motor.
How do you create electricity at any place?
by moving a piece of magnet in between a copper coil.
Can a round magnet produce electricity if it's rotating?
Yes, a round magnet rotating in a coil of wire can produce electricity through electromagnetic induction. As the magnet spins, it generates a changing magnetic field that induces a current in the coil according to Faraday's law of electromagnetic induction. This current can be harnessed as electrical energy.
