After a few years of use, the seal on your refrigerator door might start to lose its magnetism. When this happens, it can cause problems with sealing and keeping the temperature inside your refrigerator where it needs to be. A weak seal can lead to poor energy efficiency, spoiled food, […]
Magnets, whether they’re used in industrial applications or in products you have around the house, create a magnetic field that can be more or less strong. Knowing how to measure this strength is important, especially when you use magnets in applications where reliability and performance are critical. In this guide, […]
When you design applications with permanent magnets, you need to know the temperature range the magnets will be exposed to. Temperature changes affect how strong the magnet is and how well it works. If you don’t understand this, you’re going to get something that doesn’t […]
The magnetics industry is a critical part of the technology that drives our world forward. It’s the key to making things work in industries like automotive, renewable energy, and data storage. The magnetics industry has great opportunities ahead of it, but it also has some […]
Magnetization meaning：In classical electromagnetism，magnetization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material.
Demagnetization meaning：to lose magnetic properties or remove magnetic properties.
Magnetization and demagnetization are two processes that go together. If you want to understand how ferromagnetic materials such as iron, steel, […]
Neodymium magnet is still the most powerful and frequently used rare earth permanent magnetic material nowadays. Neodymium magnet can be classified to into sintered Neodymium magnet, bonded Neodymium […]
When it comes to the lifespan of permanent magnets, there is no definitive “expiration date” or “shelf life.” Under ideal conditions, a magnet can maintain its ability to generate a magnetic field for years, maybe even decades. However, a variety of factors can gradually degrade a magnet’s performance over time, […]
Magnetic Permeability Overview
Magnetic permeability is a property of materials that lets them form a magnetic field inside them and support it. Introduced by Oliver Heaviside in 1885, it’s a measure of how easily magnetic lines of force go through a material. I like to think of it as how much […]
Magnetic assemblies are designed configurations of magnetic and non-magnetic materials to create desired magnetic field patterns. By combining the strengths of multiple components, these assemblies make magnetic systems work better, making them essential in many industries. In this article, we will define magnetic assemblies, explain their importance, and look at […]
Magnetic hysteresis is a big, fancy word for a simple idea. It’s something you can see in action if you play with magnets. Hysteresis is a phenomenon where you see a time delay between when you do something to a magnet and when the magnet reacts.
The concept of hysteresis is […]
