A vertically oriented square loop of copper wire falls from rest in a region in which the field B is horizontal, uniform, and perpendicular to the plane of the loop, into a field- free region, see (Figure 1). The side length of the loop is s and the wire diameter is d. The resistivity of copper is PR and the density of copper is pm . If the loop reaches its terminal speed while its upper segment is still in the magnetic-field region, find an expression for the terminal speed. v Correct The magnetic force is determined as the product of the current, length and the magnitude of the perpendicular component of the magnetic field, FB = ILB.
