Regarding round magnet, is the quality better in Germany or in the United States

Regarding round magnet, is the quality better in Germany or in the United States because German regulations are more stringent. German regulations apply to the import and export of magnet for the sake of profit. Why do you say that? Today, I would like to elaborate on the following issue. Firstly, it may be due to respect, or it may be for the purpose of adhering to the principle of fairness, or it may be due to the rules imposed by this rule.

In the eyes of the magnetic tolerance guide, it is definitely difficult to grasp for magnet, and Xiao Fu likes it better. Usually, the quality assurance of magnet is unlikely to be met, but NdFeB magnet have a very important characteristic that allows you to come into direct contact with them. This type of magnet has a very strong magnetic field, which is very important for people with stable magnetic circuits.

The usual treatment method is zinc plating, with nickel plating being the most common protective layer. This provides great protection to the magnet, but it is not an additional protection. The magnet cannot adsorb iron filings because certain components can be damaged.

Manufacturers and distributors in northeastern Ohio should not purchase NdFeB magnet. If you underestimate the state of the magnet and what its state is, you will understand it clearly through investigation.

A device with an iron core inside and using a coil with current to make it magnetic like a magnet is called an electromagnet. Usually made into strips or hooves. The iron core should be made of soft iron or silicon steel that is easy to magnetize and easy to lose magnetism. This type of electromagnet has magnetism when energized, and disappears after power failure.

The energized solenoid with an iron core inside is called an electromagnet. When an iron core is inserted inside the energized solenoid, it is magnetized by the magnetic field of the energized solenoid. The magnetized iron core also becomes a magnet, which greatly enhances the magnetism of the solenoid due to the superposition of two magnetic fields. In order to enhance the magnetism of an electromagnet, the iron core is usually made into a shoe shape. But it should be noted that the winding direction of the coil on the hoof shaped iron core is opposite, with one side clockwise and the other side counterclockwise. If the winding direction is the same, the magnetization effect of the two coils on the iron core will cancel out each other, making the iron core non magnetic. In addition, the iron core of the electromagnet is made of soft iron, not steel. Otherwise, once the steel is magnetized, it will remain magnetic for a long time and cannot be demagnetized. The strength of its magnetism cannot be controlled by the magnitude of the current, and it will lose its intended use as an electromagnet
