1) A uniform magnetic field B points in the direction. A circular loop of wire has radius a and resistance R. At t = 0, the loop lies in the x-y plane, with the center of the loop at the origin of coordinates. The loop rotates about the y-axis with angular velocity w. Find the current, I(t), flowing through the loop at an arbitrary time t.

3. The thin, uniform rod shown below has negligible mass and and a length of 0.200 m. It is attached to the floor by a frictionless hinge at point P. A horizontal spring with force constant k = 4.80 N/m connects the other end of the rod to a vertical wall. The rod is in a uniform magnetic field of B = 0.340 T directed into the plane of the page. There is a current of /= 6.50 A in the rod, as shown. a. Calculate the torque due to the magnetic force on the rod for an axis at point P. Do this by defining a differential magnetic force on the rod for a differential length dr at an arbitrary distance r from point P. Relate this differential magnetic force to its differential torque at point P. Then sum (i.e., integrate) the contributions from the entire length of the rod to get the total torque on the rod. b.
