Electro Magnetic Induction And Alternating Currents Question 429

Question: A conducting square loop of side L and resistance R moves in its plane with a uniform velocity v perpendicular to one of its sides. A magnetic induction B constant in time and space, pointing perpendicular and into the plane of the loop exists everywhere. The current induced in the loop is [IIT 1989; MP PET 1997; MP PMT 1996, 99; MP PMT 2002]

Options:

A) $ \frac{Blv}{R} $ clockwise

B) $ \frac{Blv}{R} $ anticlockwise

C) $ \frac{2Blv}{R} $ anticlockwise

D) Zero

Show Answer

Answer:

Correct Answer: D

Solution:

No flux change is taking place because magnetic field exists everywhere and is constant in time and space.
