What is electromagnetic induction ? Explain with an activity. Write its one
application.



 



When a conductor moves through a magnetic field a voltage is produced across the conductor this is called electromagnetic induction.

The production of electricity from magnetism is called as electro magnetic induction.

Activity :
let us take a fixed coil of wire AB.
Two ends of coil are connected to current detecting instrument like galvanometer.
When bar magnet is held at rest inside the coil there will not be deflection in galvanometer readings showing no current is produced.
when bar magnet is moved quickly, we observe the deflection in galvanometer.
when bar magnet is moved away quickly, we find deflection in galvanometer in opposite side.

Applications of electromagnetic induction:
---> Induction stove works on this principle.

HEY!!

When a conducter moves through a magnetic field, a voltage is produced across the conducter this is called electromagnetic induction. This produced voltage causes a current to flow through the conductor which is called Inducted current. Electromagnetic induction can be achieved by varying the magnetic flux associated with the conductor.

Induction is in use in many forms and applications, from computer chips to doorbells. The inducted magnetic field is used to close circuits such as such as with relays and it is also used for timing. The length of time that a given electromagnetic field takes to rise and fall in strength is easily predicted, making it a very common timing tool in a wide range of electronic components. Electromagnetic induction is produced either by moving a magnet through a coil of wire on a substrate or by moving coils of wire passed stationary magnets. The latter design is much more practical and more common, as conductors are typically easier to manipulate and easier to move than are powerful, heavy magnets.
