How Are Permanent Magnet And Electromagnet Different?

As the name suggests, permanent magnet are 'permanent'. This means that they always have a magnetic field and would display a magnetic behavior at all times. On the other hand, an electromagnetic magnet only displays magnetic properties when an electric current is applied to it. That is how you can differentiate between the  two. Other than this basic difference, the strength of an electromagnet can be adjusted by the amount of electric current allowed to flow into it while permanent magnets have a fixed magnetic strength. The magnets that you have decorated on your refrigerators are permanent magnets, while electromagnets are the principle behind AC motors.
Also, if a permanent magnet loses its magnetic properties, as it does by heating to a high temperature, it will be rendered useless for ever. It cannot regain its magnetic properties ever again. Contrarily, an electromagnet loses its magnetic power every time an electric current is removed and becomes magnetic once again when the electric field is introduced again.

An electromagnet is a temporary magnet. This means that it doesn't keep its magnetic field unless you remagnetize it. Therfore, a permanent magnet keeps it's magnetic field permanently.

Regular magnets keep their magnetism. Electromagnets don't.

A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.  As the name suggests, a permanent magnet is 'permanent'. This means that it always has a magnetic field and will display a magnetic behavior at all times.

An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it. Often an electromagnet is wrapped around a core of ferromagnetic material like steel, which enhances the magnetic field produced by the coil.

Permanent magnet strength depends upon the material used in its creation. The strength of an electromagnet can be adjusted by the amount of electric current allowed to flow into it. As a result, the same electromagnet can be adjusted for different strength levels.

As for me, they are different a lot. But the main types of magnets are used in the building or cargo transportation. And companies assist to find out the main meanings and importance of magnets using. And it is great to have such helpers in understanding and further work!
