The diagram below depicts a rectangular wire loop of width a = 17.5 cm and height b = 7.95 cm, that is connected to a current source that when turned on, gives rise to a current I = 0.35 A in the wire. The loop is suspended in a uniform magnetic field B = 0.85 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 = 9 g are suspended at the lower corners. What is the angle, θ, at which the loop is in equilibrium?

Question

The diagram below depicts a rectangular wire loop of width a = 17.5 cm and height b = 7.95 cm, that is connected to a current source that when turned on, gives rise to a current I = 0.35 A in the wire. The loop is suspended in a uniform magnetic field B = 0.85 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 = 9 g are suspended at the lower corners.

What is the angle, θ, at which the loop is in equilibrium?
