The figure below shows a rectangular coil of length ℓ and width w consisting of N turns of conducting wire, moving to the right with a constant velocity v→. The coil moves into a region of uniform magnetic field B→, pointing into the page and perpendicular to the plane of the coil. The total resistance of the coil is R. Find the magnitude and direction of the total magnetic force on the coil for the following situations. (Use the following as necessary: N, B, w, l, v, and R. ) (a) as it enters the magnetic field magnitude F = direction (b) as it moves within the field magnitude F = direction (c) as it leaves the field magnitude F = direction
