Problem
A rigid U-shaped metal frame has two vertical arms of negligible thickness connected by a 10 cm horizontal base. The frame is placed in a uniform magnetic field of 0.25 T directed into the plane of the frame. A current of 5 A flows clockwise around the frame. Calculate the magnitude of the magnetic force acting on the base segment of the frame.
