how is this loop experiencing a torque (1 Viewer)

[anonymoushehe]

this was the diagram for a question asking to calculate the torque, but none of the forces act in a direction which causes the loop to experience a torque? the force is directed awya from the wire? unless im using the right hand rule wrong

yeah the diagram is pretty confusing but it looks like the wire opposite the hinge will have a force/torque going out of the page so it should produce a torque?

yeah I agree with chesy the vertical wire has a torque perpendicular to the magnetic field out of the page so you need to find the perpendicular component to find the torque

wait how does that work tho - if the force is in the direciton of the arrow (not out of the page), there wouldnt be a component producing a torque??

This is the birds eye view, and you want , so use trig as shown. Force due to motor effect can be found using
