Watch the Problem Solving Help video for insights on how to approach and solve problems related to the concepts in this module.
A rectangular loop of current carrying wire is pivoted on one of its sides. That side is horizontal, along the z-direction. The loop sits in a magnetic field in the y-direction, which is vertical. The wire loop is at an angle θ to the vertical because of the torque due to this vertical magnetic field. What is the magnitude of the magnetic field, in terms of the mass of the loop, the current I in the wire, and the angle θ?
