Question 10 A squared 8-turn coil of wire is positioned in a region of a uniform magnetic field of B pointing in the +y direction as shown below. A current of I= 25 A is established in the coil. The figure below shows the square loop as seen from the top (Note: the current for three sides of the coil are indicated). The magnitude of the magnetic dipole moment of the coil is µ=20 A m² and the square coil makes an angle of 30° with the xz-plane. = 0.4 T
