Question

What is electromagnetic damping.​

Answer 1

$\bold{ANSWER}$:

When a conductor rotates in a magnetic field, then the magnetic flux linked with it changes which induces e.m.f. If the, circuit is complete then the induced e.m.f. will proguce induced current.

According to Lenz's law the direction of induced current will be so-as to oppose the cause of its production, which is rotation of conductor, hence the conductor stops. This is $\bold{electromagnetic\: damping }$:

HOlla mate...

Electromagnetic damping is one of the most satisfing damping....When a current passed through galvenometer it's coil suffer few oscillations before coming to rest in final position.....!

As the coil moves in the magnetic field induced current is set in the coil which opposes it's motion......The oscillations of coil are damped . This is called electromagnetic.... damping.......

The electromagnetic ....damping can be further increased... by winding the coil on a light copper or aluminium frame........ as the framr moves in the magnetic.... field eddy current are set... up in the frame.... which resist the motion of the coil......

This is how a galvenometer is rendered dead beat....But then the coil doesn't ocssilate , it stays in the 1st position...! It depends upon the eddy current tho....Xd


Thanks! Hope it helps...
