Physics Question on Inductance
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
A
BLv /R clockwise
B
BLv/R anti-clockwise
C
2BLv/R anti-clockwise
D
zero
Answer
zero
Explanation
Solution
Net change in magnetic flux passing through the coil is zero.
∴ Current (or emf) induced in the loop is zero
