Question
The phenomenon of electromagnetic induction is:
- The process of charging a sphere
- The process of producing a magnetic field in a coil
- The process of producing induced current in a coil whenever there is a relative motion between the coil and the magnet
- The process of producing a cooling effect
Hint:
When a magnet is taken towards a coil, a relative motion is created between the magnet and coil which cause an induction in the current flow. This phenomenon is called electromagnetic induction.
The correct answer is: The process of producing induced current in a coil whenever there is a relative motion between the coil and the magnet
The phenomenon of electromagnetic induction is: The process of producing induced current in a coil whenever there is a relative motion between the coil and the magnet
- Electromagnetic induction occurs when the coil gets in contact with a magnet.
- The relative motion is created between the coil and the magnet which increases the strength of the magnetic field.
- That means, in the case of electromagnetic induction, an induced emf is produced as a result of a shifting magnetic field over a wire loop.
- Magnetic flux varies when a magnet and coil are moving relative to one another, which causes the coil to produce an electromotive force.
- Induced current is produced by this electromotive force.
- As a result, the current flow increases.
