The applications of electromagnets are as follows:
1, brake electromagnets: used for mechanical braking of motors in electrical drives to achieve accurate and rapid stopping. Common models are mzd1 (single-phase) and mzs1 (three-phase) series.
2, lifting electromagnet: used as a lifting device for lifting steel, iron sand and other magnetically conductive materials, or used as an electromagnetic manipulator for fixing steel and other magnetically conductive materials.
3, solenoid valve: magnetically push the solenoid valve, so that the valve opening, closing or reversing.
4, traction solenoid: the main use of traction mechanics to perform automatic control tasks.

Advantages of solenoids:
Solenoids with or without magnetism Can be controlled by on and off current; the size of the magnetism can be controlled by the strength of the current or the number of turns of the coil; can also be controlled by changing the resistance to control the size of the current to control the size of the magnetism; its magnetic poles can be controlled by changing the direction of the current, and so on.
That is to say: the strength of the magnetism can be changed, the presence or absence of magnetism can be controlled, the direction of the magnetic poles can be changed, and the magnetism can be lost due to the disappearance of the current.
