A metal rod hangs suspended from two supports as in the diagram shown. There is a constant magnetic field present that is directed upward. We will use the hanging wire to measure the strength of this magnetic field. Assume that the wire has 28 A of current and that it is 2.3 meters long and 0.8 kg in mass. The wire is observed to be deflected from the vertical by 38 degrees.

What is the magnetic field strength?
