Electromagnetic Induction and Alternating Current 7 Question 9
9. An infinitely long cylinder is kept parallel to an uniform magnetic field $B$ directed along positive $Z$-axis. The direction of induced current as seen from the $Z$-axis will be
(a) clockwise of the +ve $Z$-axis
$(2005,2 M)$
(b) anti-clockwise of the $+ve Z$-axis
(c) zero
(d) along the magnetic field
Show Answer
Answer:
Correct Answer: 9. (c)
Solution:
- In uniform magnetic field, change in magnetic flux is zero. Therefore, induced current will be zero.
