Why does the coil rotates when it is placed in between two magnet?

∙ 9y ago
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)

In which case will electric current be induced in a coil of wire?
The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.
Describe the energy transformation that takes place in a generator?
Mechanical energy to electrical energy. A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical). Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.

Why does a fan need coil and magnet?
Not all fans do need a coil and magnet - there are hand fans, punkah walla fans belt driven fans (as in your car) and Stirling engine fans that I can think of that do not need a coil or a magnet. It is only electrically driven fans that require a coil and magnet because they work on the principles of electromagnetism.
Would an electromagnet be attracted to a magnet?
Yes electromagnet would be attracted to a magnet provided direct current flows through the coil ie when the electromagnet is activated. As unlike poles attract each other the magnet is to placed accordingly. Otherwise repulsion would take place.
Thrust a magnet into a coil of wire and the coil?
... exhibits a voltage between its ends. If there is a conductor between the ends of the coil, then a current flows in the coil.
Generator consisting of a coil that rotates between the poles of an electromagnet?
dynamo
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.
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.
In which case will electric current be induced in a coil of wire?
The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.
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.

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.
