Q3 Square Loop 30 Points A copper wire is bent into a square whose sides have length L, and is placed in the xy plane with its center at the origin. A current / flows through the square in a counterclockwise direction when viewed from the +z axis. Q3.1 Square Loop 20 Points Determine the magnitude AND direction of the magnetic field due to the current flowing through the square loop at an arbitrary location Tabs = > on the z axis. Please select file(s) Select file(s) Q3.2 Square Loop 10 Points Show mathematically that the magnetic field of the square loop at the limit > > L is a dipole field, and determine the magnetic moment of the square.
