Square Current Loop Given: Find: T B 8 . 1 ? M cm d 20 12 N A i 85 . 0 30 A uniform magnetic field B = 1.8 T points in the + x direction. A square loop with sides of length d = 20 cm, N =12 turns, and current I = 0.85 A/turn pivots without friction around a pin about the z -axis as shown in the figure below.(The z -axis points out of the page in the left hand panel.) A mass M is hung from one side of the loop (C or D), and the loop is in equilibrium when it makes an angle of 30° with respect to the x-z plane. Determine the size of the mass. Enter a positive number if it is hung from C and a negative number if it is hung from D. Solutions a.) To find M we can use the following formula: 1. write the formula for torque created by the B-Field
