WebThe magnetic domains in a magnetic material can be knocked loose, by bumping or vibrating the magnet (like when sawing it in half). If knocked loose, the domains are no … WebThe field-line pattern is that of a small button magnet. We say that μ points from the south pole to the north pole of the magnet. (Magnetic field lines therefore exit the loop at the north pole and enter at the south pole.) At the center of the loop the magnetic field produced by the loop is B = (μ 0 I/(2R))n,
