The diagram depicts a rectangular wire loop of width a=17.5 cm and height b=4.50 cm, that is connected to a current source that when turned on, gives rise to a current I=0.250 A in the wire. The loop is suspended in a uniform magnetic field B =0.650 T that points in a vertical direction, and it would hang vertically if there were no current in the wire. We assume that the wire is massless, but two masses m=8.85 g are suspended at the lower corners. What is the angle, θ, at which the loop is in equilibrium?
