Why does heating a magnet decrease its magnetic field?

Answer 1

answ2. There is a characteristic named Curie Point. This is the temperature at which an object loses its magnetism. A permanent magnet, or an electromagnet, are magnetic because all the magnetic domains (co-spin regions) are aligned in the same direction.

As you heat the magnet, the molecular bonds are the place the extra energy is absorbed, eventually resulting in the bonds becoming more and more randomized.

A1. It will melt the magnetic feild around it.

Answer 2

In order for a nail or any object to be magnetized, the constituent atoms have to align. Individual atoms (which in the case of a nail would be iron atoms) are themselves tiny magnets, with their own north and south poles. If all the north and south poles point in the same direction, then the nail will be magnetic. If they all point in different directions, then there is no net magnetic field. Heat causes atoms in a solid to vibrate more rapidly and this vibration will disturb or destroy their magnetic alignment.

Answer 3

It change the alignment of electrons inside a magnet reducing it magnetic power.

Answer 4

This is known as the Curie Point. When you heat an object, the molecules become freer and eventually, all those (co-spinning) magnetic domains become randomized.

Answer 5

because when you heat the magnet the heat causes the domains to detatch and not alighn so the magnetic field decreases
