자화 의미：고전 전자기학에서, 자화는 자기 재료 내에 영구 또는 유도된 자기 쌍극자 모멘트의 밀도를 나타내는 벡터 필드입니다.
탈자화 의미：자기 특성을 잃거나 제거하는 것.
Magnetization and demagnetization are two processes that go together. If you want to understand how ferromagnetic materials such as iron, steel, […]
네오디뮴 자석 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 is a fundamental property that measures a material’s ability to support the formation of a magnetic field within itself. Scientifically, it is defined as the ratio of the magnetic flux density (B) to the magnetic field intensity (H), expressed as μ = B […]
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 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, […]
BH 곡선, 또는 자화 곡선이라고도 하는 이 곡선은 자기 재료 내에서 자기장 세기(H)와 자기 플럭스 밀도(B) 사이의 관계를 그래프로 나타낸 것입니다. 이는 재료가 인가된 자기장에 어떻게 반응하는지를 보여줍니다.
BH 곡선이란 무엇인가요?
The BH curve is the relationship between […]
전자기석과 영구 자석의 차이점에 대해 궁금해하신 적이 있다면, 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 […]
