In electromagnetic induction, the induced charge in a coil is independent of

A

change in the flux

B

time taken to change the flux

C

resistance in the circuit

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
Induced emf, `e=-(dphi)/(dt)`
But, `e=iR and i=(dq)/(dt)`
`therefore" "(dq)/(dt)R=-(dphi)/(dt) or dq=(dphi)/(R)`
So, induced charge in a coil is independent of time taken to charge the flux.

Induced Electromagnetic Field

The phenomena of electromagnetic induction is: (a) the process of charging a body. (b) the process of generating magnetic field due to a current passing through a coil. (c) producing induced current in a coil due to relative motion between a magnet and the coil. (d) the process of rotating a coil of an electric motor.

Electromagnetic brakes work on the principle of electromagnetic induction. If a metallic disc or a coil is rotating in a uniform magnetic field, it will experience a torque due to induced currents set up in the disc. According to Lenz's law, induced current is in a direction so as to oppose the rotation. Hence a retarding torque is produced. The rotating wheel of a vehicle is connected to a coil placed in a uniform emf is used to charge a battery. Thus kinetic enery of wheel is stored as chemical energy. The drawback of electromagnetic brake is that induced current or retarding torque is directly proportional to speed of rotation. The speed, therefore, decays exponentially and vehicle will take a long time to stop. Thus, mechanical brakes are used simultaneously. The advantage of electromagnetic brakes is that
