How to measure surface magnetic force using a Gauss meter? The working principle of the Gauss meter is mainly based on the application of the Hall effect: when a current-carrying conductor is placed in a magnetic field, due to the Lorentz force, a transverse potential difference appears in a direction perpendicular to the magnetic force. field and current. A gaussmeter is an instrument for measuring magnetic fields based on the principle of the Hall effect. Hall probes generate a Hall voltage due to the Hall effect in a magnetic field. The measuring ...
Surface treatment of magnets - Do all type of magnets need coating? Sintered NdFeB permanent magnet materials are produced by powder metallurgy process. It is a powder material with very strong chemical activity. There are tiny pores and cavities inside, which are easily corroded and oxidized in the air. The experimental results show that a 1cm³ sintered NdFeB permanent magnet will be completely oxidized and corroded when placed in air at 150°C for 51 days. After the magnetic material is corroded or the components are damaged, the magnetism will attenuate or...
What aspects need to be communicated for your projects? - How to prepare an inquiry for magnets? - What details must be clarified when buying magnets? When we want to clarify the requirements of magnets, there are a few key points, including performance requirements, shapes and sizes, magnetization directions, surface treatment requirements, quantity required, transportation methods, and special packaging requirements. One is the technical parameters of the parts. On the other hand, it involves the purchase habits of different customers. 1. Grade performance In most cases, customers designate the grade, or the clients indicate the Remane...
What does grade N42 , N45 or N52 mean? A: Take grade N35 as example, letter "N" is short for neodymium, directing to the magnet type, the number “35” means a neodymium magnet has a maximum energy product of 35MGOe. It refers to the maximum magnetic energy that the material can be stored. The most common range of N-serials grade usually operate at up to +80 degrees C. Higher temperature grades (NxxM, NxxH, NxxSH, NxxUH, NxxEH, NxxAH) are rated from up to +100 degrees C to a maximum of up to +240 degrees. Magnet shape, working envi...
