A straight conductor of length 'l' is oriented parallel to the Y-axis and moving along the X-axis in the positive direction in a uniform magnetic field of flux density 'B'. The B-field emerges out of the XY-plane and is perpendicular to it.
a) If the linear motion velocity is 'v' m/s, what is the magnitude of emf induced in the conductor?
b) If in part (a), the flux density varies harmonically as B = B0 cos(ωt), find the induced emf in the conductor.
