Witryna5 lis 2024 · A fundamental property of a static magnetic field is that, unlike an electrostatic field, it is not conservative. A conservative field is one that does the same amount of work on a particle moving between two different points regardless of the path chosen. Magnetic fields do not have such a property. Witryna5 lis 2024 · (b) When magnetized by an external field, the domains show greater alignment, and some grow at the expense of others. Individual atoms are aligned within domains; each atom acts like a tiny bar magnet. Ferromagnetism arises from the fundamental property of an electron; it also carries charge to have a dipole moment.
