The interactions of electricity and magnetism are difficult to explain in nontechnical terms. In most atoms, electrons occur in pairs. The magnetic flux density B may be defined in terms of the Lorentz force F acting on a charge q that moves in a magnetic field with a velocity v [1]: F q v B ( ) (1) The unit of the magnetic field, in the SI system, is the tesla (T) while in the cgs system it is the gauss (G) with 1 G = 10-4 T. The strength of the magnetic field decreases … In 1845, Michael Faraday demonstrated that it was a property of matter and concluded that every material responded (in either a diamagnetic or paramagnetic way) to an applied magnetic field. Download revision notes for Magnetism and Matter class 12 Notes and score high in exams. Paramagnetism, kind of magnetism characteristic of materials weakly attracted by a strong magnet, named and extensively investigated by the British scientist Michael Faraday beginning in 1845. Magnetism is a fascinating invisible force – it influences the environment around it. Elements: Element is a substance made up of same type of atom. Anything that is magnetic has a magnetic moment, like a bar magnet or a coil of electric current. Chapter 14 - An Introduction to Matter . All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. Magnetic dipoles in these materials are arranged into domains where the arrangements of individual magnetic dipoles are essentially perfect that can produce strong magnetic fields. The main distinction is that in some materials there is no collective interaction of atomic magnetic moments, whereas in other materials there is a very strong interaction between atomic moments. Magnetic force on a proton example (part 2) Mass spectrometer. Electric conduction, also, is described microscopically in the terms of a Drude-Lorentz model.
