磁化 意味：古典的電磁気学において、磁化は磁性材料内の永久または誘導された磁気双極子モーメントの密度を表すベクトル場です。
消磁 意味：磁気特性を失う、または磁気特性を取り除くこと。
Magnetization and demagnetization are two processes that go together. If you want to understand how ferromagnetic materials such as iron, steel, […]
ネオジム磁石 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曲線、または磁化曲線は、磁気材料における磁場強度（H）と磁束密度（B）の関係をグラフで表したものです。これは、材料が印加された磁場にどのように応答するかを示しています。
BH曲線とは何ですか？
The BH curve is the relationship between […]
もしあなたが疑問に思ったことがあるなら 電磁石と永久磁石の違いについて, 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 […]
