An electro magnet is an electrically charged coil of wire, called a solenoid, it usually has a magnetic metal core in the centre, iron would be good. The coil has to have an electrical current run through it to magnetise the metal.

electromagnet
This is called an electromagnet. When a current passes through a coil of wire, a magnetic field is generated around the coil. This magnetic field creates a temporary magnet that can attract or repel other magnetic materials.
In an electromagnet, the electromagnetic forces increase as the current flowing through the coil increases. Additionally, the strength of the magnetic field can also be enhanced by increasing the number of turns in the coil or using a ferromagnetic core. Collectively, these factors contribute to a stronger electromagnet.

An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.

Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
Linc Robinson built the first electromagnet.
The electromagnet was invented in the year 1850 by william sturgeon :)

An electromagnet can be turned on and off.
