Consider an infinitesimal segment of the loop, of length ds . The magnetic field is perpendicular to the segment, so the magnetic force on it has magnitude dF = iB ds . The horizontal component of the force has magnitude (c o s) h dF iB ds = and points inward toward the center of the loop. The vertical component has magnitude
