By relying on high-performance permanent magnets such as neodymium-iron-boron to generate a magnetic field, the magnetic core is rotated via a mechanical handle, altering the polarity direction to achieve attraction and release. No external power supply is required—instead, the magnetic field remains consistently stable.

A magnet unit with a diameter of 20 millimeters and weighing only 100 grams can firmly hold a 6-kilogram car body panel, performing high-precision "air ballet" at the end of a robotic arm. In the laboratory of Hunan Qianhao Electromechanical, engineers placed a 0.8-millimeter-thick car door panel on the test bench. With the command issued, a group of electropermanent magnets, only the size of coins, were instantly activated, and the thin steel plate was smoothly adsorbed and lifted, remaining motionless even with manual shaking. Even more surprising, when the engineer suddenly cut off the power, the sheet metal remained firmly attached to the magnetic suction unit—this is the "power-off non-demagnetization" core technology demonstrated by Qianhao's latest generation QEPMZ-C20 electropermanent magnet.
