Question

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 2-axis will be

• A. clockwise of the +ve z-axis
• B. anti-clockwise of the +ve z-axis
• C. zero
• D. along the magnetic field

Answer 1

Answer: (C)

In uniform magnetic field, change in magnetic flux is zero. Therefore, induced current will be zero.
$\therefore$ Correct answer is (c).
