Question

A circular loop of wire having a radius of 8.0 cm carries a
current of 0.20 A. A vector of unit length and parallel to the
dipole moment *μ* of the loop is given by *0.60*
*i**-0.80* *j*. (This unit vector gives the
orientation of the magnetic dipole moment vector.) If the loop is
located in a uniform magnetic field given by
*B**=0.25* *i**+0.30* *k* T.
Find (a) the torque on the loop (in unitvector notation) and (b)
the orientation energy of the loop.

To find the torque on a current carrying flat loop of wire in a
uniform magnetic field you need to multiply the current times the
cross product of the area vector of the loop with the magnetic
field vector -- I ( A x B ). How

A ? What would happen to the loop if it were
placed in the magnetic field with A perpendicular
to B and...
