How does heat affect a magnet?
A permanent magnet (i.e. not an electromagnet) will be demagnetised by heating it.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Is the magnet in a compass a permanent magnet or a electromagnet?
The magnet in a compass is a permanent magnet. Its magnetic field aligns with the Earth's magnetic field, allowing the compass needle to point north.
How can i do permanent magnet?

How do you heat and cold affect a Magnet?
Heating a magnet can cause it to lose its magnetic properties by disrupting the alignment of its magnetic domains. Cooling a magnet can strengthen its magnetic field by improving the alignment of these domains. Extreme temperatures can also cause permanent damage to a magnet.
What kind of magnet is the domain remains aligned?
A permanent magnet.
