Background

An electromagnet is a device that generates electromagnetic electricity when energized. The coil with current has magnetism like a magnet in a process that the iron core is magnetized by the magnetic field of the coil after the iron core is inserted into the coil. In addition, in order to immediately demagnetize the electromagnet after power failure, soft iron or silicon steel materials with relatively fast demagnetization are often adopted for manufacturing. The electromagnet has magnetism when being electrified, and the magnetism disappears after the electromagnet is powered off. Electromagnets have extremely wide application in our daily lives. For example for use in engine fuel cut-off, with control of power on and off by fuel cut-off electromagnets

However, when the existing oil stopping electromagnet is used for blocking or communicating oil flowing in a pipeline, a small amount of oil often overflows when the iron core moves, so that the corrosion and rust speeds of moving parts can be accelerated, and the moving parts inside the electromagnet body cannot move smoothly.
