A circular loop of radius R is rotating with angular speed w to about Z-axis in a time-independent magnetic field, given by B = B_0 (cosa i + sina j). At t = 0, the loop lies in the Y-Z plane. Determine the magnetic flux psi and the induced EMF due to the magnetic field across the loop as a function of time.

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...
