A 40-turn loop of wire has an area of 4.5 x 10-2 m2 and an unknown amount of current is flowing around it. The current loop is in a region of a uniform magnetic field of magnitude 0.75 T and is experiencing a torque of 0.90 N.m.
a) What orientation of the current loop gives the maximum torque on it? Explain your reasoning. If it helps, provide a clear sketch showing the direction of the magnetic field and the direction of the area vector of the loop.
b) If the current loop is experiencing the maximum possible torque of 0.90 N.m for the given conditions, what is the current in the wire?
Work shown appreciated!
