Physical damage, exposure to extreme heat, or exposure to strong magnetic fields can cause a permanent magnet to lose its magnetism. Once a permanent magnet is demagnetized, it is very difficult to restore its original magnetic properties.

What is better for lifting heavy metal objects eletromagnet or permanet magnet?

An electromagnet would generally be better for lifting heavy metal objects as its magnetic strength can be easily controlled by adjusting the electrical current. A permanent magnet may not have sufficient magnetic strength to lift heavy objects, and it does not offer the flexibility of adjusting its magnetic force.


How can be destroyed?

---- Magnetism can be destroyed by following methods:---- * By heating the magnet, * By hammering the magnet.--->In accordance to this point...allowing the magnet to fall violently* By keeping similar poles of magnets together for a long time. * [not sure about this]by keeping magnet under running water.


Why is an electromagnet not a permanet magnet?

because the copper wire in it is only magnetic when there is electricity running through it so when you turn of the electricity soure it is no longer magnetic

Can a magnet's magnetism be destroyed?

Yes, a magnet's magnetism can be destroyed by subjecting it to high temperatures or strong magnetic fields. This can disrupt the alignment of the atoms within the magnet, causing it to lose its magnetic properties.
