It is only magnetized when electricity is run through it. Once you stop the electron flow it reverts back to its original state.
You can turn a piece of iron into a temporary magnet by stroking it with a permanent magnet in the same direction multiple times. This process aligns the magnetic domains within the iron, creating a temporary magnetic field.
A temporary magnet.
To make a temporary magnet, you can rub a piece of iron or steel with a permanent magnet. This process aligns the magnetic domains in the material, creating a temporary magnetic field. To enhance the temporary magnetism, you can increase the number of times you rub the material with the 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.
The energy source of a temporary magnet is the external magnetic field that is applied to it. When a temporary magnet is exposed to a magnetic field, its magnetic domains align in the direction of the external field, resulting in the magnetization of the material. Once the external field is removed, the temporary magnet loses its magnetic properties.
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.
It will become an electro-magnet which is an temporary magnet. it is because of the induction property, the magnetic effect gets transfered to the Scale. (it can be any piece of Iron)
An electro magnet proves that Electricity and Magnetism always co-exist in nature

An electro-magnet can be turned on and off.
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
A temporary magnet.
A electro magnet is used for lifting things by the magnetic force provided by the amount of coils and the size of the battery
