A current i runs counterclockwise along the perimeter of an equilateral triangle whose sides are length a. The the triangle is laying on a horizontal plane. A uniform magnetic field, B, points out of the page. (a) Draw a diagram showing the current, the field, and the force on each side of the triangle. (b) Find the magnitude of the force on each side and the net force on the entire triangular loop. (c) Find an expression for the dipole moment of the loop of current and its direction. (d) Determine if there is a net torque on the loop (do the forces on it cause it to rotate.) Explain BOTH using the forces and using the torque on a dipole equation. (e) Use the results of this problem and either the similar exercise (with the field to the right, in the plane of the loop) and/or example 26.5 in the text to answer the following question: Under what circumstances is there a net magnetic force on a current loop? Under what circumstances is there a net torque?
