WebMay 28, 2024 · If you've ever played with a magnet, you know that magnets, when placed end-to-end, like to align parallel, but when placed side by side like to align anti-parallel: Now let's zoom into some magnetic material. It's made up of … WebDomain walls move easily within the magnet and have a low coercivity. By contrast, a particle that is single-domain in all magnetic fields changes its state by rotation of all the magnetization as a unit. This results in a much larger coercivity. The most widely used theory for hysteresis in single-domain particle is the Stoner–Wohlfarth model.
