Coercivity by Magnet Type Introduction to Magnetic Coercivity Coercivity (coercive force), determines how well a magnet can resist external forces that would cause it to lose its magnetic properties. The forces that can demagnetise, or degauss a permanent magnet include; temperature, alternating currents and kinetic force. High coercivity is necessary for magnets that will be [...]
Which Coatings Magnets are Available? There are many types of coatings available and each one has their own unique properties and uses for different applications. Nickel (Ni-Cu-Ni) Epoxy Teflon (PTFE) Zinc (Zn) Black Nickel (Ni) Titanium Nitrate (TiN) Gold (Au) Copper (Cu) Which Coatings Magnets are Available Nickel-Copper-Nickel (Ni-Cu-Ni) Coated Magnets Ni-Cu-Ni is [...]
What Shape and Size Magnets are Available? Available Magnet Shapes Permanent magnets come in a huge variety of shapes and each has its own unique benefits. The geometry of a rare earth magnet determines how the magnetic field lines are arranged from the north pole to the south pole, so the shape of the magnet [...]
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 [...]
NO Export License Needed! Dy / Tb / Sm-Free NdFeB Magnets Hey there, sourcing managers and engineers, We are handling international sales at MPCO Magnets. We talk to buyers every day, and one question comes up constantly: “Do you have the rare earth export license?” Our answer is always the same, and it’s a good [...]
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 [...]

Magnetic Shielding - Magnetic shields isolate an object or source from the magnetic/ Electromagnetic shields. It does not eliminate or destroy the magnetic field, the shield just allows the field to complete its path through an easy path called “path of least magnetic reluctance”. e.g. In current sensing typical U-Shield protects the sensor from parasitic [...]
Top 10 China Neodymium Magnets Supplier China produces over 85% of the world’s neodymium magnets. That’s not a typo. They absolutely dominate this market. But finding the RIGHT manufacturer? That’s where things get tricky. As a professional neodymium magnets manufacturer, I’ve spent months researching Chinese NdFeB magnet suppliers. Visiting factories. Comparing capabilities. And today, I’m [...]
