The diagram on your assignment depicts a rectangular wire loop of width a = 13.5 cm and height b = 6.85 cm, that is connected to a current source that when turned on, gives rise to a current I = 0.20 Amps in the wire. The loop is suspended in a uniform magnetic field B = 0.30 T that points in a vertical direction as shown in the diagram, and it would hang vertically if there were no current in the wire. We assume that the wire is massless, but two masses m = 8.05 g are suspended at the lower corners. What is the angle (in °), theta, at which the loop is in equilibrium? Ok I know that the sum of the forces and the torque need to equal zero for this system to be in equilibrium, after that I'm lost. How do I get started with this problem?
