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...

The drawing shows a coil of copper wire that consists of two
semicircles joined by straight sections of wire. In part a the coil
is lying flat on a horizontal surface. The dashed line also lies in
the plane of the horizontal surface. Starting from the orientation
in part a, the smaller semicircle rotates at an angular frequency ω
about the dashed line, until its plane becomes perpendicular to the
horizontal surface, as shown in part b. A uniform magnetic...

a) Two flat surfaces are exposed to a uniform, horizontal magnetic field of magnitude 0.22 T. When viewed edge-on, the first surface is tilted at an angle of 21° from the horizontal, and a net magnetic flux of 6.6 x 10-4 Wb passes through it. The same net magnetic flux passes through the second surface. (a) Determine the area of the first surface. (b) Find the smallest possible value of the area of the second surface. b) Near San Francisco,...
