A magnet which doesn't lose it's magnetic effect when it's away from another magnet .
Steel magnets are usually permanent magnets , while those made of iron lose their magnetism , as soon as the original magnet is held away . I simply mean that :-
For example , when you use a magnet to attract a paperclip ( or a nail ) made of iron , and you attach a second paperclip to the first one , while still holding the first one to the magnet , the 2nd will still be held to the 1st .
As soon as you remove the magnet , the magnetism between the 1st and the 2nd clips will be broken down , and they will fall down .
But if you use nails ( or paperclips ) made of steel , the magnetism between the 1st and the 2nd nail will still be there , even if the original magnet is held away from the 1st .
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
An example of a permanent magnet would be the Earth. The Earth is one giant magnet with opposite poles.
By definition an electromagnet is only working when it has a supply of electricity, a Permanent Magnet is always a magnet
Perminant magnet
You cannot magnetize a permanent magnet because it is already magnetized.
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
