A circular loop of wire having a radius of 6.0 cm carries a current of 0.14 A. A unit vector parallel to the dipole moment of the loop is given by 0.40i -0.92j. If the loop is located in a magnetic field given by B = (0.40 T)i + (0.35 T)k,
A) find the magnitude of the magnetic dipole moment of the loop.
B) Find the i component of the torque on the loop.
C) Find the j component of the torque on the loop.
D) Find the k component of the torque on the loop.
E) Find the magnetic potential energy of the loop.
