Please clearly draw magnetic dipole moment for both loops and explain how its done. A small square loop of wire carrying some current is located between the poles of a horseshoe mag- net as shown in the diagram. Throughout this problem you may assume that the magnetic field between the poles is constant. Note that the loop is shown skewed only to pro- vide some perspective. When the loop is vertical, its face is actually parallel to the poles of...
A circular loop of wire of radius R carries a current I in a region where a uniform magnetic field of magnitude B0 is present. (a) If the magnetic dipole moment of the loop makes an angle θ < π/2 with the magnetic field, do a drawing that includes the loop of current, its magnetic dipole moment, the magnetic field, and the direction of the torque experienced by the loop. Make sure to indicate the current i and the angle...

A square loop of wire with a small resistance is moved with constant speed from a field free region into a region of uniform B field (B is constant in time) and then back into a field free region to the left.
