The difference between neodymium iron boron magnets and ferrite magnets
Time： 2023-03-17
Neodymium iron boron magnets are also known as "strong magnets" and "permanent magnets". If stored properly, the outer coating is not damaged, and used at regular temperatures, demagnetization will not occur, and the service life is permanent. The most widely used magnets nowadays are neodymium iron boron magnets and ferrite magnets. Let's take a look at the differences between them?

Ferrite magnets are metal oxides with ferromagnetism. In terms of electrical properties, the resistivity of ferrite is much higher than that of metal and alloy magnetic materials, and it also has higher dielectric properties. The magnetic properties of ferrite also exhibit high permeability at high frequencies.
Neodymium iron boron is a third-generation rare earth permanent magnet material with the characteristics of small size, light weight, and strong magnetism. It is currently a magnet with good performance to price ratio and is known as the magnetic king in the magnetic field. The advantages of high energy density have made neodymium iron boron permanent magnet materials widely used in modern industry and electronic technology. In a bare magnetic state, the magnetic force can reach around 3500 Gauss.
Therefore, ferrite has become a widely used non-metallic magnetic material in the high-frequency weak current field. It belongs to non-metallic magnetic materials and is a composite oxide (or ferrite) of magnetic iron oxide and one or more other metal oxides. Magnetic force is usually between 800 and 1000 Gauss and is often used in instruments such as speakers and speakers.
Different magnets have different uses. Shenzhen Youda Magnet Products Co., Ltd. is a professional company engaged in the production, sales, and research and development of various types of magnetic materials and products.
