4. At time t= 0, a wire circular loop of radius R is horizontal in a constant uniform magnetic field, Bo, that is directed straight up. The loop is rotating at a constant angular velocity, ao, around an axis that is perpendicular to the magnetic field. a. Find the direction of the current flow (cw or ccw) as the loop rotates to position 2. b. Find the magnitude of the induced EMF as a function of time.
