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 [...]
Magnetic Assemblies
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 [...]
What is magnetic hysteresis
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 [...]
What is BH curve
A BH curve, also known as a magnetization curve, is a graphical representation of the relationship between the magnetic field strength (H) and the magnetic flux density (B) in a magnetic material. It shows how the material responds to an applied. What’s a BH curve? The BH curve is [...]
Difference Between Electromagnet and Permanent Magnet
Magnets are everywhere in today’s technological landscape. From electric motors and generators to medical imaging devices and consumer electronics, magnets are a key component in many of the things we use every day. There are two main types of magnets that are used across many industries: electromagnets and permanent magnets. [...]
Uses of Permanent Magnets
10 Uses of Magnets Magnets are found in so many things we use every day—from the medical devices that help us stay healthy to the industrial systems that keep our world running. One of the most popular types of magnets is a neodymium magnet. These are the strongest [...]
Halbach Arrays
Halbach Arrays Magnets are used in all sorts of modern technology. They power electric motors, medical devices, and high-tech scientific equipment. Among all the different types of magnets, the Halbach array is unique because it optimizes magnetic field strength and directionality. The Halbach array was first proposed by [...]
