There are not only "Phantom of the Palace Lady" but also "Scientific Shadow" on the red wall of the Forbidden City

Nowadays, most of the headphones used by everyone are moving coil or moving iron, and a small number of coil irons are headphones. What is the difference between them? What's the downside? Let's find out together.

NdFeB magnets contain rare earth element neodymium, a kind of active metal, which is easily oxidized in humid air. Therefore, NdFeB magnets are usually surface treated, such as electroplating. For surface treatment, we have some test methods to check whether it meets our requirements.

The reduction in cost means the enlargement of profit margins, and it will have stronger competitiveness in the market. Here we discuss how to reduce costs healthily and effectively from the aspects of management improvement, process optimization, technological innovation, and manufacturing innovation.

The DC motor is a device that realizes the mutual conversion between DC electric energy and mechanical energy. According to the purpose, it can be divided into two types: DC motor and DC generator. Among them, the motor that converts mechanical energy into DC power is called a DC generator.

Excessive carbon dioxide leads to climate change that has greatly threatened the survival of human beings on the earth. Only by developing green and low-carbon can this threat be alleviated. At the same time, this is also an opportunity for the development of the magnet industry.

NdFeB Magnet need surface treatment before use, because of its' easy to oxidize characteristics

Geomagnetic declination refers to the angle between the magnetic north and true north anywhere on the earth. When the local magnetic north is eastward, the geomagnetic declination is positive, otherwise it is negative. In most areas of mainland China, the geomagnetic declination is between -10° and +2°. In Taiwan, it is about -4°～-3°.

In fact, in permanent magnets, there will be some deviations between the magnetization direction of the magnet and the actual physical direction.
