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
$(1989,2 M)$
(a) $B L v / R$ clockwise
(b) $B L v / R$ anti-clockwise
(c) $2 B L v / R$ anti-clockwise
(d) zero
Show Answer
Answer:
Correct Answer: 6. (d)
Solution:
- Net change in magnetic flux passing through the coil is zero.
$\therefore$ Current (or emf) induced in the loop is zero.
