مبدأ عمل sucker solenoid electromagnet is to generate a magnetic field by energizing the internal coil, so that the iron core is magnetized and generates a strong suction force, thereby adsorbing the magnetic conductive parts. Specifically, when the coil is energized, a magnetic field is generated, and this magnetic field will be added to the iron core, so that the iron core is magnetized and generates a strong suction force, which can adsorb the magnetic conductive parts. The iron core is usually made of soft iron or silicon steel, the adsorption surface is integrally connected to the yoke iron part, and the hollow part is sealed with epoxy resin glue. The specific process is as follows:

1.1.1. Power on to generate a magnetic field
When current passes through the coil, a magnetic field is generated around the coil. The direction of the magnetic field is determined by the direction of the current (following the right-hand rule).

The presence of the iron core can significantly enhance the strength of the magnetic field because the iron core has a high magnetic permeability and can concentrate the magnetic lines of force.

1.1.2. The attraction of the magnetic field to ferromagnetic materials
When the adsorption surface of the suction cup electromagnet is close to the ferromagnetic material (such as steel, iron, etc.), the magnetic field will penetrate the target object.

The target object is magnetized, generating a magnetic pole opposite to the magnetic field of the electromagnet, thereby forming a strong attraction between the two.

1.1.3. Maintaining the adsorption force
As long as the coil is powered, the magnetic field will continue to exist and the adsorption force will continue to be maintained.

When the current is disconnected, the magnetic field disappears, the adsorption force disappears, and the target object is released.
