Magnetic Field Lines of Pot Magnet As for the term "pot magnet", many people may have heard for the first time that the pot magnet is a kind of magnet wrapped in a steel shell and shaped like a pot, so we call it pot magnet (cup magnet), also called magnetic component. Through magnetic circuit [...]
Safe and Effective Use of Electromagnetic Equipment The usefulness of electromagnetic equipment cannot be denied. Employed in everything from massive construction cranes to the doorbell in your house, electromagnets use a simple on/off function to perform complex tasks every day. In the process of magnetic separation, electromagnets or permanent magnets are used to extract sources [...]
Industrial Magnetics in the Paper Industry The uses for industrial strength magnets in paper production can be divided into three primary categories: Paper Mills: In paper mills, the most common application for magnetic technology is in the use of suspended magnets and conveyor belt magnets to move raw materials, like wood chips, along in the [...]
Why Use Rare Earth Magnetic Separators? demonstrating rare earth magnetic separators Magnetic separators are frequently used in the manufacturing industry to separate potentially damaging materials that are magnetically susceptible. A high degree of precision is required because metal contamination can be a real problem. It can damage equipment and affect the quality of the product [...]
What is the MAGNETIC MOMENT The magnetic moments is a property that we use to verify the quality of our magnets. It is a way to measure the strength of a magnet and is widely used throughout the industry. Moreover, it is an easy, quick, and repeatable measurement. The magnet grade and magnet volume define [...]

Electro Holding Magnet – Things You Need to Know What Is A Holding Electromagnet? Holding electromagnets are used to attract and hold ferromagnetic pieces. The maximum force efficiency is achieved with the piece to be hold above the attraction’s face and in direct contact with both poles (outside pole and inside pole). How Does A [...]
Electromagnetic Transmissions Solenoids Holding Magnets Solenoids for simple operation Single-acting solenoids are for common applications. The magnetic field delivered by the coil upon power-up attracts the core. Then, the nucleus becomes free again in the absence of current. They are thus available in different designs, folded sheet, square profiled, machined in the mass. Solenoids for [...]
