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 (commonly 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, such as 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.

Company information
"A company that is both old and new"! The predecessor of Mitsubishi Nagasaki Machinery was established as Mitsubishi Shipbuilding Co., Ltd. Nagasaki Steel Works during the Taisho era, and it traces back to Mitsubishi Steel Co., Ltd. Nagasaki Steel Works, which became independent in 1942. In 1975, it was established by inheriting the industrial machinery and steel structure manufacturing division of the company. The technology of Mitsubishi Nagasaki Machinery is based on the skills developed as a cast and forged steel manufacturer since the Mitsubishi Steel era. While supported by tradition and new technologies, it continues its unique research and development and technical refinement, skillfully blending engineering (design technology) and manufacturing (production technology) in a well-balanced manner, actively engaging in product development and business expansion.
