WebThe iron bar is filled with magnetic domains. Each is like a little magnet, but usually they point all different directions That means that their outside magnetic fields pretty much cancel, so the bar isn't a magnet itself. When the iron is near a permanent magnet, in which the domains are lined up, some of the domain magnetizations in the bar ... WebThe magnetic field inside a ferromagnet lags the vacuum field, and this lagging is called the hysteresis. Let's explore this hysteresis curve of ferromagnets. Created by Mahesh Shenoy.
