Torque on a Current Loop in a Uniform Magnetic Field(53)
A wire is formed into a circle having a diameter of 10.0cm and is placed in a uniform magnetic field of 3.00mT. The wire carries a current of 5.00A. Find
(a) the maximum torque on the wire and
(b) the range of potential energies of the wire-field system for different orientations of the circle.
