A permanent magnet (i.e. not an electromagnet) will be demagnetised by heating it.
A. Compasses typically use a permanent magnet.
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Yes, it is a permanent magnet.
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
yes
By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
