1. The problem statement, all variables and given/known data A current i flows through a triangular loop in the y-z plane. The loop is situated in a uniform magnetic field B. http://s5.tinypic.com/14csew3.jpg a) Find the total force on the loop when the magnetic field is in i) the x-direction, and ii) the y-direction b) What is the magnetic dipole moment of the loop? (use mu=i x area and the appropriate direction) c) What is the torque on the loop and how will it tend to turn when the field is in i) the x-direction, and ii) the y-direction? 3. The attempt at a solution a)x-direction: F=current x length x uniform magnetic field x sinθ F=-i x B x l y-direction: F=i x B x l cos 45 b) area of a triangle: 1/2(b*h) since the angle is 45 degree so both height and base are the same. 1/2(l^2) mu=i*1/2(l^2) however, I don't really know how to figure out the direction for this question. c) torque=number of loops*current*area*uniform magnetic field x-direction: torque=1*i*1/2(l^2)*B y-direction: torque=1*i*cos45*1/2(l^2)*B I am not really sure whether I did the problem correctly or not...and for some questions I only know how to do part of them Any comment or help would be great! Thank you very much.
