explain in terms of magnetic domains why heating a magnet decreases its magnet field.?

Answer 1

Inside a magnet, there are many little zones called magnetic domains, which are areas where the spins of the electrons are aligned to produce a net force. Magnetization occurs when enough of these domains are oriented in the same direction. When you heat up a magnet, the thermal energy excites the electrons, making it more difficult for them to maintain their orientation to each other. Ferromagnetic materials have a Curie Temperature, which is the temperature at which it loses all
ability to magnetize. The Curie Temperature for Iron is 1043 K.

Answer 2

The magnetic domains get more random with the increased heat. That means that their alignment will not be uniform and point wherever they feel like. In that way, the magnetic field decreases.

Answer 3

At higher temperatures, the domains get unaligned because of thermal motion. The temp at which the magnetism disappears is called the Curie temperature.

Answer 4

Electron bypass from the sunlight interior the direction of the ambience must be stated, to teach this might take extra study, maybe the molten middle has little to do with with the magnetic field generated. this is in simple terms yet in a distinctive thank you to seem at a complicated subject.

Answer 5

Well heat is a source of energy and it kinda works like this. Magnets loose strength when the bonds of force are broken. So really ur ? should b how r these bonds broken and what causes it.
