Magnetism and Electromagnetism - Technical MCQs

Q1:

What are the effects of moving a closed wire loop through a magnetic field?

A A voltage is induced in the wire.

B A current is induced in the wire.

C The polarity across the wire depends on the direction of motion.

D All of the above

ANS:D - All of the above

All are collect answers due to that there is the change in magnetic field as loop cuts the field in accordance to Faraday law wherever there is change in magnetic field emf induced then current is also induced hence polarities seen.
