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 square loop made of copper wire is falling (moving downward
due to gravity) out of a region where there is a constant magnetic
field of magnitude Bext = 0.235 T. The magnetic field is
perpendicular to the plane of the loop, either into or out of the
page (it doesn't matter which direction).
The loop is falling with a constant
velocity because of the current induced in the loop
and the magnetic field.
What is the velocity of the...
