Question

Chapter 21, Problem 33

A square coil of wire containing a single turn is placed in a uniform 0.29-T magnetic field, as the drawing shows. Each side has a length of 0.31 m, and the current in the coil is 14 A. Determine the magnitude of the magnetic force on (a) the top and (b) left sides

Explanation / Answer

we consider side 1 magnetic field yields no force F = 0 N on that since it is parallel to teh current on side 2 magnetic field is perpendicular to teh current it yields maximum force F = ILB     = 14A * 0.31m * 0.29T = 1.25N on side three manetic field field yields no force F = 0 on that side since it is parallel it is parall ot the current on side four magnetic field is perpendicular to teh current it yields maximum force   F = ILB     = 14A * 0.31m * 0.29T = 1.25N     = 14A * 0.31m * 0.29T = 1.25N
