Question:
A rectangular, 50-turn coil has sides 6.0 and 8.0 cm long and carries a current of 1.75 A. It is oriented as shown in Figure and pivoted about the z axis.
(a) If the wire in the xy plane makes an angle ? = 37o with the y axis as shown, what angle does the unit normal n make with the x axis?
(b) Write an expression for n in terms of the unit vectors i and j.
(c) What is the magnetic moment of the coil?
(d) Find the torque on the coil when there is a uniform magnetic field B = 1.5 T j.
(e) Find the potential energy of the coil in this field.
