Permanent Magnets vs. Electromagnets
The only magnet you are able to find naturally is called a lodestone. This is a naturally magnetized piece of the mineral magnetite. But all the permanent magnets you buy has been refined and is usually an alloy, a combination of different metallic elements.

Answer:
Difference between Permanent Magnet and Electromagnet is magnetic field and strength. In Electromagnet, the magnetic field is created by a wire-wound coil but the magnetic field of Permanent (Bar) Magnet cannot be changed. The strength of Permanent Magnet depends on the material used for its creation, on the other hand, the strength of Electromagnet varies according to the flow of electric current into it. Three types of Permanent (Bar) Magnets are Ceramic Magnet, Flexible magnets, Neodymium iron boron magnet, and Samarium cobalt magnet. Each has its own applications and types. Let’s see the more differences between the Permanent Magnet and Electromagnet.
