Descrição: dc.descriptionConcepts in basic electromagnetic theory-
Descrição: dc.descriptionIn this Demonstration,an external magnetic field H is increased until the magnet becomes saturated, with all the domains aligned for a maximum induction Bs. The iron bar will retain its magnetization indefinitely, even after the external field is removed. In order to demagnetize the bar, a magnetic field in the opposite direction must be applied. The iron resists demagnetization, with B lagging behind changes in H. When H is reduced to zero, the flux density is reduced slightly to Br, known as the remanence. Only when the magnetic field is increased to a value Hc in the opposite direction, known as the coercivity, does the iron lose its magnetization and do its domains return to random orientations. The area enclosed by one cycle on the B vs H plot is equal to the energy dissipated as heat-
