A square loop of wire with a small resistance is moved with
constant speed from a field free region into a region of uniform B
field (B is constant in time) and then back into a field free
region to the left. The self inductance of the loop is
negligible.
When entering the field the coil experiences a magnetic force to
the left.
When leaving the field the coil experiences a magnetic force to the
right.
Upon entering the field,...

A circular thin wire loop of radius a=37.2 cm and total resistance R=0.186 12 is positioned in the (xy)-plane, where it is exposed to the external (applied) uniform magnetic field directed along the z-axis. Over some period of time t, the z-component of that field varies as Bextz(t)=Bo – at + ßta, where Bo=6.68 T, a=60.727 T/s and ß=69.008 T/s2. Right at the geometrical center of the loop circle, there is a very accurate magnetometer that can detect the difference...
