A vertically oriented square loop of copper wire falls from rest in a region in which the field B is horizontal
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...

A circular loop of wire with area A lies in the y-plane. As viewed along the z axis looking in the -z direction toward the origin, a current I is circulating clockwise around the loop. The torque produced by an external magnetic field B is given by tau = D(4i - 4j), where D is a positive constant, and for this orientation of the loop the magnetic potential energy U = -mu middot B is negative. The magnitude of the...
