Question

"A rectangular loop of wire carries a 1.0 A current clockwisearound the loop. The loop is in a uniform magnetic field ofmagnitude 2.5T that points out of the page. What is the magneticforce on wach side of the loop? Net force?" I am not sure if I need to use the F=ILBsin for eachside. I am also unsure of the significance of knowing the directionof each force if we know the directions of the current and magneticfield.

Explanation / Answer

Yes, you use F = I L B    for eachside. Note that for each side, the current is perpendicularto the magnetic field so that .    sin = sin90 = 1   (which I why I left it off) . Also for directions... the right hand rule shows thats theforce on: .    the top side is "down" . the right side is "left" .    the bottom side is "up" . and the left side is "up". . Finally, note that the total force on the current loop is zero(this is true of the total force on any current loop in a magneticfield... total force is always zero).
