The molecular theory of magnetism was given by Weber and modified later by Ewing. According to that theory -
Each molecule of a substance is a complete magnet in itself. Though, in a magnetized atom the molecular magnets are randomly oriented to give zero net magnetic moment. On magnetizing, the molecular magnets are realigned in a particular direction leading to a net magnetic moment.
can i get assistance here with questions involving the design of a permanent magnet magnetic bearing?
These materials are used for permanent magnet manufacturing because of their low cost and their low weight. It consists of low iron oxide in combination with either barium carbonat
