Which of the following destroys the magnetic property?(1 Point)a) Heatingb) Hammeringc) Dropping on a hard surfaced) All of the above

d) All of the above

Explanation:

a) Heating: When a magnet is heated, the kinetic energy of the atoms increases and the alignment of magnetic domains gets disturbed, causing a loss of magnetic properties.

b) Hammering: Hammering a magnet can cause the alignment of the magnetic domains to be disrupted, which can lead to a loss of magnetism.

c) Dropping on a hard surface: Dropping a magnet on a hard surface can cause physical changes and misalignment of the magnetic domains, which can result in a loss of magnetic properties.

So, all of the above actions can destroy the magnetic property of a material.
