Torque-free solenoid manufacturers tell you that the electromagnet device has the basic properties of turning on the current to generate magnetism, and turning off the current to generate magnetism, and the magnetic disappearance of the current can be changed by changing the connection method of the positive and negative poles of the battery or changing the winding direction of the coil to change the north and south poles of the electromagnet. Because of the above characteristics, the application range of electromagnets in the industrial field is very wide.

If you want to use the electromagnet better, you must first understand the structure of the electromagnet:
1. W-type electromagnets are divided into single W-shaped (only the core is W-shaped) and double W-shaped (the core and the armature are both W-shaped). Torque-free solenoid manufacturers tell you that electromagnets with this structure are generally used as electromagnetic systems for AC relays, AC contactors and other AC electromagnetic mechanisms.
2. Solenoid solenoids, Torque-free solenoid manufacturers tell you that they are generally used as traction solenoids and operating solenoids for automatic switches, but there are also a few overcurrent relays that use this type of solenoid.
3. The snap-fit ​​electromagnet, the Torque-free solenoid manufacturer tells you that the electromagnet of this structure is mostly used for DC relays and DC contactors, and sometimes also used for AC relays.
