WebJan 30, 2024 · The molecular theory of magnetism was developed by Weber, and Ewing later modified it. According to the molecular theory: 1. Each molecule of a magnetic material behaves like one complete magnet in itself. Thus, each molecule, irrespective of its state of magnetism (i.e., it may be magnetised or unmagnetised), behaves like an … Webof all modern theories. According to Weber's theory the molecules of a magnetic substance are permanent magnets, which have their axes at random in the unmagnetised state, but … WebMagnetic materials and composed of groups of tiny magnets at a molecular level around the atoms, and a magnetised material will have most of its tiny magnets lined up in one direction only to produce a north pole in one direction and a south pole in the other direction.In a non-magnetized state, the molecular magnets are in different orientation. digital choice rewards
