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.
