Domain Model Of Magnetism

When cooled below a temperature called the curie temperature the magnetization of a piece of ferromagnetic material spontaneously divides into many small. The domain theory of magnetism explains what happens inside materials when magnetized. In the ferromagnetic material pictured above the domains are randomly aligned the illustration shows how this phenomenon works not the actual size or shape of domains normally invisible magnetic field lines depicted in red are seen emanating from the poles of the bar magnet use the magnet position slider to move the magnet closer to the ferromagnetic material so that it interacts with.
