Magnetic Separator: The Difference Between Electromagnets and Permanent Magnets

I will introduce the differences between electromagnets and permanent magnets used in various fields such as motors, cars, trains, and electronic devices!

Introduction to the Differences Between Electromagnets and Permanent Magnets An "electromagnet" is a type of magnet that generates "temporary" magnetic force by winding a coil around a core made of magnetic material (often iron) and passing an electric current through it. By stopping the current, it is possible to reduce the magnetic force to nearly zero. A "permanent magnet," on the other hand, is an object that generates a magnetic field without the need for external energy like electricity. Unless subjected to heat or shock, it does not lose its magnetic force for a semi-permanent duration. [Features] <Electromagnet> ■ It is possible to reduce the magnetic force to nearly zero by stopping the current. ■ Compared to a permanent magnet of similar size, it can generate a larger magnetic force. ■ Continuous current through the coil generates heat, which increases resistance and reduces the magnetic force (weakens it). *For more details, please refer to the PDF document or feel free to contact us.
