WebO Magnetic field lines exit the north pole of a magnet and reenter the south pole of a magnet. Unlike electric field lines, magnetic field lines can cross each other. Ferromagnetic materials can be magnetized more easily than other materials because their magnetic domains can be generally aligned. Previous question Next question A magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction. When cooled below a temperature called the Curie temperature, the … See more Magnetic domain theory was developed by French physicist Pierre-Ernest Weiss who, in 1906, suggested existence of magnetic domains in ferromagnets. He suggested that large number of atomic magnetic moments (typically … See more There are a number of microscopy methods that can be used to visualize the magnetization at the surface of a magnetic material, revealing the magnetic domains.
