A long piece of wire of mass 0.058 kg and total length of 3.55 m is used to make a square coil with 80 turns. The coil is hinged along a horizontal side, carries a 3.89 A current, and is placed in a vertical magnetic field with a magnitude of 0.0124 T. Determine the angle that the plane of the coil makes with the vertical when the coil is in equilibrium?. B.Find the torque acting on the coil due to the magnetic force at equilibrium?C.What is the required radius of a cyclotron designed to accelerate protons to energies of 35.5 MeV using a magnetic field of 5.29 T? ?
