The process by which a iron piece touching a permanent magnet behaves as a magnet as long as it maintains contact is called magnetic induction.
not only does this work when the iron is physically touching the magnet but it works as long as the piece of iron remains under the influence of the magnet.
A iron piece attracted to a magnet through a paper with out any physical contact will also behave as a magnet.
A temporary magnet, such as an electromagnet, can only attract materials when in contact with another magnet or when an electric current is flowing through it. It loses its magnetism when the current is turned off or the magnetic field is removed.
domain
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
A permanent magnet is a material that maintains a persistent magnetic field without the need for an external power source. For example, "The refrigerator door securely closed thanks to the strong permanent magnet embedded in the seal."
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
Perminant magnet
That's called a permanent magnet.
Permanet Magnet

Something called a permanent magnet
A temporary magnet is called a soft magnet. It can be easily magnetized and demagnetized, unlike a permanent magnet that retains its magnetism for a longer period of time.

A. Compasses typically use a permanent magnet.
It is called ferromagnitisum .
Yes, it is a permanent magnet.
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
