Torque Limited Magnetic Coupler in Crusher The double-geared roller crusher has the advantages of light weight, small size and low energy consumption, and is suitable for various operating environments, and has been widely used in coal mines. In the open pit coal mine, the large volume of raw coal is crushed by the double-geared roller [...]
What Is a Ring Magnet, Donut Magnet, Annular Magnet A ring magnet (you’ll also hear “donut magnet,” “annular magnet,” or “magnetic ring”) is basically a washer-shaped permanent magnet—round on the outside with a hole through the center. That hole is what makes it so useful: you can slip it onto a shaft, rod, or screw [...]
Amazon's IATA Reporting Requirements for Magnetic Products Recently, many Amazon sellers have run into confusion during the “magnetic product” review process. Amazon often asks for a magnetic testing report that complies with IATA standards, and some review notes specifically mention measuring the magnetic field strength (in gauss) at 2.1 meters from any surface of the [...]
Is Steel Magnetic? Ever held a magnet up to different metal objects and wondered why it sticks to some but not others? Most steel IS magnetic because it contains iron—but not all steel behaves the same way around magnets. Some types like austenitic stainless steel (304, 316) won’t attract magnets at all, while carbon steel [...]
Can Copper Be Magnetised Pure copper cannot be permanently magnetized because it is a diamagnetic material with paired electrons that repel magnetic fields. Copper is different from iron or nickel because it doesn’t have the atomic structure needed for ferromagnetism or permanent magnetism. Let me clear something up right away. If you’re picturing a copper [...]
N52 vs N54 vs N55 Magnets: Choosing the Right Grade for Performance, Cost and Temperature So you’re shopping for neodymium magnets and you keep seeing these grades: N52, N54, N55. Which one should you choose? And more importantly, does that higher number actually mean better performance for your project? Let me break it down for [...]

Are Batteries Magnetic Are batteries magnetic? The short answer: Batteries themselves aren’t magnets, but many batteries ARE attracted to magnets. There’s a big difference between those two things, and I’ll explain exactly why in this guide. In this post, as a professional neodymium magnets manufacturer, I’ll also show you: Which battery types stick to magnets [...]
Are Magnets Bad for Batteries? Are magnets bad for batteries? The short answer is no — magnets won’t damage your batteries or drain their charge. But there are 2 catches: Short circuits from conductive magnets touching battery terminals and physical damage from strong magnets impacting battery casings. As a professional neodymium magnets manufacturer, let me [...]
