ferromagnets

Physics believes that ferromagnets are substances that have regions of spontaneous magnetization and these domains have been called domains ... Within the domains, the electrons of all atoms are oriented so that their magnetic fields are oriented in one direction ... Each domain is magnetized to saturation ... For the appearance of a magnetic field around such a substance, its domains, i.e. magnetize it. If all domains are oriented in the same way, then the object is a permanent magnet.
What is the conclusion from this information? This means that in a permanent magnet, the electrons of all domains are oriented in one direction ... From this information is positive the following - all free electrons are oriented in one direction, which means that they all "rotate" in parallel planes ...
