Question
Hey All, heres the problem Im having with my physics: An eight turn coil encloses a circular area having a radius of20.0 cm. The coil lies in the plane of the page and has a 6.00-Acurrent flowinmg clockwise around it. If the coil is in a uniformmagnetic field of 2,00x10-4 T directed towards the leftof this apge, what is the magnitude on the torque of thecoil? If you could list the formulas you use, that would begreat...there should be at least 3 different ones used,right? Thanks for any and all help ;) Hey All, heres the problem Im having with my physics: An eight turn coil encloses a circular area having a radius of20.0 cm.

Explanation / Answer
The magnetic torque is given by = x B = (I ) N A B sin here = 90o =(6.0A)(8)(2 x 3.14 x 0.2m)(2.00x10-4 T)(sin90o) =(6.0A)(8)(2 x 3.14 x 0.2m)(2.00x10-4 T)(sin90o)
