Question

As seen in Figure 2, a rod with minimal resistance rotates at an angular velocity of @= 5.0 rad/s across a circular area with a radius of a = 0.2 m. A second rod with low resistance is immobile. Two rods are interconnected in the middle of a circle. A magnetic field with a strength of B = 0.3 T permeates the paper. r = 0.40 m/m is the resistance per unit length of the circular arc. Determine the induced emf and current direction. Indicate the induced current and its direction on the diagram. X X X-X X X x xx xx x X X B xx x X XXX x x X X X X X X X Fig 2. Problem 2
