Eddy current magnet
In the world of magnetic applications, specifically electric motors and transformers, it’s important to understand what the magnetic fields are doing with their surroundings. One of the things that affects magnet performance is the generation of eddy currents. Eddy currents change how magnetic systems work, and they also present opportunities [...]
Remagnetize Fridge Door Seal
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, [...]
How to Measure Magnet Strength?
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, [...]
How temperature affects magnet performance
How temperature affects magnet performance 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 [...]
Magnet Industry Predicting in 2030
Magnet Industry Predicting in 2030 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 [...]
Magnetization and demagnetization
Magnetization and demagnetization 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 [...]
How to make NdFeB magnet
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 magnet, and hot pressed Neodymium magnet in accordance with the manufacturing process. Each form has their different magnetic properties, then their overlapped [...]
How long do magnets last
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, [...]
What is magnetic permeability
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 [...]
