Shrinking Loop. A circular loop of flexible iron wire has an initial circumference of 162 cmcm , but its circumference is decreasing at a constant rate of 11.0 cm/scm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 0.700 TT , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop. Part A Find...

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...
