Question

when a magnet may lose its property ​

Answer 1

a magnet may lose its property from the following reasons

1) if it is dropped from a height

2) if it is placed on fire

3) if the magnet is beaten by any thing like hammer

4) if the hammer is heated

Answer 2

Answer:

YES VIA 3 PROCESSES

Explanation:

1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. At this point, the energy being put into the magnet from the heat will permanently disrupt the magnetic domain structure of the material, turning it into a paramagnetic material [a similar effect occurs in materials called hard ferrites

2) Via a demagnetizing magnetic field: permanent magnets exhibit a characteristic called coercivity, which is the ability of a material to withstand being demagnetized by an applied magnetic field.

3) Via shock: this really only applies to older materials such as magnetic steels and Alnico materials; the mechanism that creates coercivity means that they are susceptible to being demagnetized if enough energy is transmitted through the material via a shock, such as being dropped or hit with a hammer.
