Chapter 28, Problem 28.46(choose chapter or problem)
A square loop of wire, of side d, carries a current I.(a) Determine the magnetic field B at points on a line perpendicularto the plane of the square which passes through thecenter of the square (Fig. 28-53). Express B as a function of x,the distance along the line fromthe center of the square, (b) Forx d, does the square appearto be a magnetic dipole? If so,what is its dipole moment?FIGURE 28-53 46.
