A rod of length l rotates with a uniform angular velocity omega about its perpendicular bisector. A uniform magnetic field B exists parallel to the axis of rotation. The potential difference between the two ends of the lrod is

Options

A. `2Bomega l^(2)`
B. `1/2Bomega l^(2)`
C. `B omega l^(2)`
D. zero

Answer

D

Explanation

Since there is no magnetic flux change due to rotation of rod hence the potential difference between two ends of the rod is zero.
