vot✰ a) A uniform magnetic field exists perpendicular to the paper, Boz [Wb/m²]. The slider in the above picture completes the loop and is moving in the positive x direction, with the velocity shown. Determine the EMF induced in the loop. b) If the field disappears for x。 < x (uniform field exists for x < xo), determine the EMF once the slider passes the xo position (and continues moving in the positive x direction).
