Electro Magnetic Induction And Alternating Currents Question 321

Question: A metallic square loop ABCD is moving in its own plane with velocity v in a uniform magnetic field perpendicular to its plane as . An electric field is induced [IIT JEE (Screening) 2001]

Options:

A) In AD, but not in BC

B) In BC, but not in AD

C) Neither in AD nor in BC

D) In both AD and BC

Show Answer

Answer:

Correct Answer: D

Solution:

Both AD and BC are straight conductors moving in a uniform magnetic field and emf will be induced in both. This will cause electric fields in both, but no net current flows in the circuit.
