The following are the general steps for manufacturing laminated magnets: Material Preparation Thin Sheets of Magnetic Materials Select appropriate magnetic materials, such as neodymium iron boron (NdFeB), ferrite, etc. The thickness of these thin sheets usually ranges from 0.1 to 1 mm, depending on the application requirements. For example, in high-frequency application scenarios, thinner […]

Reduce Eddy Current Losses In an alternating magnetic field, an induced electromotive force will be generated inside the bulk magnetic steel, which then forms eddy currents, resulting in energy losses and heat generation. However, laminated magnetic steel is composed of thin magnetic steel sheets stacked one on top of another. Since the sheets are insulated […]

The following are the main reasons why SmCo magnets are used in SMT fixtures: Firstly, SmCo magnets have a high magnetic energy product, which means that they can generate a relatively strong magnetic field in a relatively small volume. In SMT fixtures where certain requirements are placed on the spatial layout, a compact and […]

The application fields of SmCo magnets will present the following new development trends in the future: Aerospace and Defense Sectors With the continuous advancement of aerospace and defense technologies, the requirements for material performance are becoming increasingly stringent. Thanks to its outstanding performance in extreme conditions such as high temperature and radiation, SmCo magnets will […]
Throttle Position Sensors Working Principle: In non-contact throttle position sensors, samarium-cobalt magnets work in conjunction with Hall elements. When the throttle shaft rotates, it drives the samarium-cobalt magnet to rotate along with it. The rotation of the magnet causes changes in the magnetic field. The magnetic field collector converts the horizontal magnetic field into […]
Carbonyl iron powder Characteristics Carbonyl iron powder is a very commonly used magnetic particle in magnetorheological fluids. It has characteristics such as high purity, fine and uniform particle size. Its particle size is generally in the micron level, for example, commonly 3 – 5 microns. Carbonyl iron powder has a relatively high saturation magnetization intensity, […]
