1. The problem statement, all variables and given/known data Number of wraps of coil on magnetic moment in field: 100 - N_c Number of wraps of coil on Helmholtz coil: 140 - N_h Current through magnetic moment: .796A - I_c Area of magnetic moment: .37m - A_c Radius of Helmholtz coil: .1635m - R_h Current through Helmholtz coil to attain equilibrium on balance: 1.32, 2.61,3.91 corresponding to gravitational torques caused by counterweights that are .255m away, .0001g,.0002g,.0003g 2. Relevant equations Bh=(8u_0*N_h*I_h)/(5^(3/2) * R_h) as well as T_m = B_h * N_c*I*A_c 3. The attempt at a solution I calculated the three torques both gravitational as well as magnetic based on the formulas provided above. Each time I recieved an answer that was a magnitude of 100 apart. Based on my thinking the T_g and T_m should be equal as the magnetic torque should balance out the gravitational torque. I have checked to make sure all of my units are in SI and I still cannot determine why im not getting the calculations that I should. I also cannot make heads or tails of how the Area of the magnetic moment within the field should have a vector and if it does, how to describe its orientation in space.
