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.
