Question

a magnet is heateing _____
magnetization​

Answer 1

Answer:

If a magnet is exposed to high temperatures, the delicate balance between temperature and magnetic domains is destabilized. At around 80 °C, a magnet will lose its magnetism and it will become demagnetized permanently if exposed to this temperature for a period, or if heated above their Curie temperature

Answer 2

Answer:

If a magnet is exposed to high temperatures, the delicate balance between temperature and magnetic domains is destabilized. At around 80 °C, a magnet will lose its magnetism and it will become demagnetized permanently if exposed to this temperature for a period, or if heated above their Curie temperature. Heat the magnet even more, and it will melt, and eventually vaporize.

Explanation:

The ease with which a magnet becomes demagnetized decreases with increased temperature. Different materials react differently under heat, so what the magnet is made of is important; different magnetic materials have different Curie temperatures, the average being between 600 to 800 °C. Magnets consisting of Alnico – an iron alloy containing aluminum, nickel and cobalt – has the best strength resistance, then SmCo (Samarian cobalt) and NdFeB (neodymium-iron-boron), followed by ceramics. NdFeB magnets have the highest resistance to demagnetization but the largest change with temperature.
