What is the remanence of a disc magnet?
Aug 07, 2025| Yo, what's up everyone! I'm a supplier of Disc Magnets, and today I wanna talk about something super interesting - the remanence of a disc magnet.
First off, let's break down what remanence actually is. In simple terms, remanence is like the magnet's "memory" of its magnetic state. When you magnetize a disc magnet, it retains a certain amount of magnetic field even after the external magnetizing force is removed. This remaining magnetic field is what we call remanence.
Now, why is remanence such a big deal? Well, it's crucial for a whole bunch of applications. For instance, in motors and generators, a high remanence means the magnet can generate a stronger magnetic field, which in turn leads to better performance. In magnetic sensors, remanence helps in accurately detecting and measuring magnetic fields.
As a disc magnet supplier, I know how important it is to understand remanence. Different applications require different levels of remanence. Some need a really high remanence to get the job done, while others can make do with a lower one. That's why we offer a wide range of disc magnets with varying remanence levels to meet the diverse needs of our customers.


Let's take a closer look at the factors that affect the remanence of a disc magnet. One of the main factors is the material. Different materials have different magnetic properties, and this directly impacts the remanence. For example, neodymium disc magnets are known for their high remanence. They're made from a combination of neodymium, iron, and boron, which gives them a really strong magnetic field even after magnetization.
The manufacturing process also plays a huge role. How the magnet is formed, heat-treated, and magnetized can all affect its remanence. At our place, we use state-of-the-art manufacturing techniques to ensure that our disc magnets have the best possible remanence. We pay close attention to every detail, from the raw materials to the final product, to make sure that our customers get top-quality magnets.
Another thing to consider is the shape and size of the disc magnet. Believe it or not, these can also have an impact on remanence. A larger disc magnet might have a higher remanence compared to a smaller one, but it also depends on the material and how it's magnetized. We offer a variety of sizes and shapes, like the 4mm X 2mm Disc Magnet, to give our customers more options.
Now, I wanna talk about how we test the remanence of our disc magnets. We use specialized equipment to measure the magnetic field strength and determine the remanence. This helps us ensure that each magnet meets our high standards and the specific requirements of our customers. We also provide detailed test reports with every order, so our customers can have peace of mind knowing exactly what they're getting.
As a supplier, I always keep an eye on the latest trends and technologies in the magnetic industry. There are constantly new developments in materials and manufacturing processes that can improve the remanence of disc magnets. We're always looking for ways to stay ahead of the curve and offer our customers the best products possible.
