Thinking of V that is probably wrong, the number of loops has nothing to do with the potential, so V = IR. So EMF is -N \cdot \frac{d \Phi}{d t} because we take \Phi at each loop, and just sum those up. I am wondering now why can we actually do that, since in a different alignment the flux in...

Homework Statement There is one square coil of area A that rotates with speed \omega around axis y. The magnetic field is uniform and points to the z direction. Show that the torque is \frac{A^2B^2N^2\omega sin\omega t}{R}. Homework Equations T = |\underline{m} \times \underline{B}|...
