Nothing up to some critical temp (around 600 degrees I believe),
after which the "magnet" looses its magnetism.

How a solenoid may be used to demagnatise a bar magnet?
Heating a bar magnet with solenoid demagnatise it.
Can heating a magnet cause it to loose its magnetic properties?
Yes, a magnet looses it's power even when it is hammered.
How could heating a bar magnet reduce its magnetism?
Heating a bar magnet could reduce its magnetism because the heat, by raising the energy level in the metal, disorients the atoms, which disrupts the magnetism.
Why does a magnet lose its' magnetism by hammering and heating?
The magnets' domains become unaligned.
Can heating or hitting a permanent magnet ruin it?
When you heat a magnet past its' Currie point the domains become unaligned. Same when you drop it.
Does heating up a magnet make it stronger?
Heating up a magnet actually makes it weaker. A magnet can be completely demagnetized when heated past it's Curie temperature.
How does heat affect a magnet?
A permanent magnet (i.e. not an electromagnet) will be demagnetised by heating it.
Can a magnet lose its magnetism by heating?
Yes
What happens when heating a magnet?
it will loose its magnesium
Which of the following can be done to demagnetize a permanent magnet?
heating the magnet past the Curie point
How a solenoid may be used to demagnatise a bar magnet?
Heating a bar magnet with solenoid demagnatise it.
What are three ways to destroy the magnetism of a magnet?
I suggest that you incinerate it.
How do you demagnatise a magnet?
You can demagnetize a magnet by: -dropping it many times -heating it over a flame -hammering it many times
Can heating a magnet cause it to loose its magnetic properties?
Yes, a magnet looses it's power even when it is hammered.
How could heating a bar magnet reduce its magnetism?
Heating a bar magnet could reduce its magnetism because the heat, by raising the energy level in the metal, disorients the atoms, which disrupts the magnetism.
How can iron be demagnetized?
an iron can be demagnetised by ;-hammering it while facing east _west direction -hitting it hard on the ground -connecting it into an ac current while facing the east _west direction .
What are 2 ways to make or destroy a magnet?
heating it or freezing it i believe
