A rectangularl oop carring a clockwise curent i is placed in a constant magnetic field B = By. The four corners of the loop are at (x=0, y = +/- a/2, z=+/-b/2 where a and b are positve onstants(adsbygoogle = window.adsbygoogle || []).push({});

find the force and torque, magnitude and direction on each of the four straight lin segments of the loop. Illustrate this device and your answers using a diagram.

force only acts on the vertical (according to the diagram) and points out from the page for y = a/2. For y = -a/2, the force points into th page.

for its magnitude

F = 2 i a B / 2 = i a B Since theta is 90 degrees. B is constant.

the torque points downward in the negative z direction

t=2 (b x F)/2 = b x F = iabB

am i right?
