The current loop is in the y-z plane. The direction of the magnetic field is in the z-direction.
A) Which way is the torque on the current loop?
B) If the current is 4 amps and the magnetic field strength is 2.5 Tesla, what is the magnitude of the torque?
here is the picture (which I drew): http://twitpic.com/7e0zv9 [Broken]
Right Hand Rule 2
T=IAB, T=NIABsinθ. The torque formulas I have necessitate finding an area of the current loop. But, as you can see from the picture (which displays all info. given) there is no way to find the area.
The Attempt at a Solution
A) Well, the loop is parallel to the field. If I use the right hand rule 2, the direction of the torque would be into the page, would it not?
B) I feel that I am missing something crucial. I have done a few problems similar to this one, but I was always given some number to work with to find the area of the current loop.
Seriously, ANY help is very much appreciated. Thank you.
