Magnetic field electromagnet is a kind of electromagnet. Its main purpose is to generate an electromagnetic field and generate a strong magnetic field, so it is called a magnetic field electromagnet. The magnetic field electromagnet generally has two magnetic poles, and a magnetic field of a certain size is generated between the two magnetic poles. In this magnetic field space, scientific magnetic experiments can be carried out.

How does the magnetic pole polarity of the magnetic field electromagnet change? Generally speaking, the polarity of the magnetic field can be changed by changing the polarity of the output current of the electromagnet; the main ways to change the direction of the magnetic pole are: high-current mechanical switch, AC contactor, and electronic switch.
To make the magnetic field electromagnet work stably, first:
1. The design is reliable and stable, with a certain margin.
2. When manufacturing, it is produced in strict accordance with the requirements of the drawings.
3, the configuration of the power supply stability is better!
The relevant content about how to change the magnetic pole polarity of the magnetic field electromagnet is introduced here, I hope it can help you.
