Section 27.8 Using Magnetic Forces
Activity 27.8.1 . Force on a Circuit.
The square circuit at right is in a region with a uniform magnetic field.
(a) Determine the current through each side of the square circuit.
(b) Determine the direction of the magnetic force on each side of the square circuit.
(c) Does the magnetic field exert a net nonzero magnetic force on the loop? If so, what direction is the net force?
(d) Does the magnetic field exert a net nonzero magnetic torque on the loop? If so, what direction would you expect the loop to rotate (starting from rest)?
