Electromagnetic Induction and Alternating Current 2 Question 5

####6. 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 to and into the plane of the loop exists everywhere.The current induced in the loop is

(1989,2M)

(a) BLv/R clockwise

(b) BLv/R anti-clockwise

(c) 2BLv/R anti-clockwise

(d) zero

Show Answer

Answer:

Correct Answer: 6. (d)

Solution:

  1. Net change in magnetic flux passing through the coil is zero.

Current (or emf) induced in the loop is zero.
