What is the difference between a Permanent Magnet and an electromagnet?

The electromagnet creates a magnetic field with the help of electric current, which usually passes through a magnetic coil. The north and south poles are then formed at the ends of the coil, and as soon as the power supply ceases, the magnetic field also ceases, so electricity is required for the operation of the electromagnets.

A permanent magnet is what most people think when they hear the word "magnet." This category includes Ferrite magnet, Neodymium Magnet, SmCo magnet, AlNiCo magnet and other types of magnets. Magnets on refrigerators, boards, speakers, headphones, hard drives, compasses, furniture and mobile phone cases are all permanent magnets. Permanent magnets,both Ferrite Permanent Magnets and Sintered Neodymium Magnets usually do not lose their power and create a continuous magnetic field around them.

The advantage of permanent magnets is that they can create a magnetic field even without the electrical energy required for the operation of the magnet. The advantage of electromagnets is that they can be switched on and off, and they can create a magnetic field much stronger than permanent magnets.
