The magnetic field in a region is given by $B = 3 r$ , where $r$ is the distance from the origin. The direction of the magnetic field is along the negative $z-axis$ . A conducting rod of length $20 cm$ lies as shown in the figure. If the rod is rotating with an angular velocity of $4 rad/s$ , find the emf induced between the ends of the rod.

Question

The magnetic field in a region is given by

B = 3 r

, where

r

is the distance from the origin. The direction of the magnetic field is along the negative

z-axis

. A conducting rod of length

20 cm

lies as shown in the figure. If the rod is rotating with an angular velocity of

4 rad/s

, find the emf induced between the ends of the rod.

The magnetic field in a region is given by B=B0Ly(k) where L is a fixed length. A conducting rod of length L lies along the Y-axis between the origin and the point (0.L,0). If the rod moves with a velocity v=v0i, find the emf induced between thee ends of the rod.B0v0l2B0v0lB0v0l4B0v0l6
