Magnetic hysteresis is a property of ferromagnetic materials where the material’s magnetic response depends not only on the current magnetic field but also on its past exposure to magnetic fields. In simple terms, when you apply a magnetic field to materials like iron, they become magnetized. However, […]
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 the relationship between […]
If you’ve ever wondered about the difference between electromagnets and permanent magnets, you’re not alone. Choosing the right type of magnet can make all the difference in everything from industrial machinery to everyday gadgets. In this post, you’ll get a clear, straightforward comparison that cuts through the technical jargon to explain […]
Permanent magnets play a crucial role in electric motors, especially in brushless DC (BLDC) motors, which are widely used today. These magnets create a consistent magnetic field that interacts with the motor’s windings to generate smooth, efficient rotation without the need for brushes. This design reduces wear […]
The magnetic materials industry continues to evolve, with significant advancements and emerging trends. The following summary highlights recent developments, primarily focusing on the elevator traction machine and small-scale wind power generation markets.
Market Growth and […]
Choosing the right NdFeB magnet for your wind turbine isn’t just about picking the strongest one off the shelf. The ideal magnet needs to withstand harsh environments, deliver consistent magnetic performance, and ensure long-term reliability — all while balancing cost and durability. If you’re involved in wind turbine design, manufacturing, or […]
AdBlue is a diesel exhaust fluid (DEF) used in selective catalytic reduction (SCR) systems to reduce harmful emissions from diesel engines. Permanent magnets play a critical role in enhancing the performance and reliability of AdBlue systems. This article explores how permanent magnets are […]
Permanent magnets are materials that produce a stable magnetic field without the need for an external power source. Their ability to maintain magnetization makes them essential components in a wide range of modern technologies.
When it comes to home wind turbines, the type of permanent magnet used in the generator plays a crucial role in determining the efficiency and performance of the device. There are several types of permanent magnets commonly used in domestic wind […]
The performance testing of finished magnets mainly detects surface magnetism and magnetic flux.
Surface magnetism: Use a surface magnetometer (Gaussmeter, Tesla meter), which is used to test the surface magnetism on the surface of the magnet. Its probe can only test one point, and […]
