What Is a Ring Magnet (Donut Magnet) & How to Use It
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
Grades of Magnets
Magnets come in various grades, especially for neodymium magnets (NdFeB). The term “magnet grades” typically refers to the material’s (BH)max or maximum energy product, which is a key value for comparing the strength of neodymium magnet grades. While magnet grades
How Do Speakers Use Magnets
How do speakers use magnets? I see magnets as the heart of every speaker. They help turn electrical signals into the sounds I hear every day. Three main parts work together: the permanent magnet, the voice coil (an electromagnet), and
10 Uses of Magnets in Daily Life (With Real Examples)
Magnets show up in everyday life more than most people realize. They’re the “behind-the-scenes” reason your fridge stays sealed, your headphones make sound, and motors spin inside everything from fans to washing machines. In short: the most common uses of
How to Separate Magnets Stuck (Strong/Small)
Magnetic fields are powerful forces that are applied in science, industry, and everyday life. However, when they cling together, their strength makes it difficult for them to part. It does not matter whether you have small magnets, heavy neodymium magnets,
Permanent Magnet Motor vs Induction Motor
The key differences between a permanent magnet motor and an induction motor center on efficiency, performance, cost, and application. 🏆 I see permanent magnet motors offer higher efficiency, often exceeding 90%, with superior torque output and long-term energy savings. Induction
