I Review I Constants 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. 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. Substituting the result of the previous part B² s² vt gives FB R Part L Find the resistance R of the loop.
