A rectangular wire loop of dimensions 0.20m×0.10m and resistance 2Ω is placed entirely inside a region of uniform magnetic field 0.40T directed perpendicular to the plane of the loop and pointing into the page. The loop is pulled out of the field region with a constant speed of 5ms−1, the motion being perpendicular to the 0.10m side.
(i) State whether the induced current in the loop is clockwise or anticlockwise as viewed from the side where the field lines enter the page.
(ii) Calculate the magnitude of the current in the loop at the instant when the side of length 0.10m is just leaving the field region.
