Rexroth MFB12-37YC/220V wet electromagnet coil with 23 holes

Advantages of electromagnet:
There are many advantages of electromagnets: whether the electromagnetic ferromagnetism can be controlled by the pass or off current;The magnitude of the magnetism can be controlled by the strength of the current or the winding number of the coil.It can also change the resistance control current size to control the magnetic size.Its magnetic pole can be controlled by changing the direction of the current, etc.That is, the magnetic strength can be changed, the magnetic field can be controlled, the direction of the magnetic pole can be changed, the magnetism can be lost by the disappearance of the current.An internal coil with an iron core that USES an electric current to make a magnetic device like a magnet called an electromagnet, usually made of strips or hoofs.The core should be made of soft iron or silicon steel that is easy to magnetize and easily disappear.The electromagnet is magnetic when it is energized, and then it disappears.Electromagnet has many advantages: electromagnet magnetism has, can use pass, break current control.The magnitude of the magnetism can be controlled by the strength of the current or the number of turns of the coil.Electromagnets are widely used in daily life.Electromagnet is an application of current magnetic effect (electromagnetism) and is closely related to life, such as electromagnetic relay, electromagnetic crane, maglev train, etc.
