An equilateral triangular coil of wire is very tightly wrapped
and has side lengths L, 2 turns, and a steady current I.
The coil is placed in a uniform magnetic field pointing
upwards:
I
~B
You can define your coordinate system however you want but it
should be right handed (meaning ˆı ׈ = ˆk).
a) What is the magnetic dipole moment of the coil?
b) What is the net force on the coil and what is the net torque
around the center of the coil?
c) What is the potential energy of the coil as shown in the figure?
What is the potential energy of the coil in its minimum
and maximum potential energy orientations?
