Permanent magnets are the backbone of modern industries, from medical imaging to renewable energy. However, their performance is not defined solely by magnetic strength—corrosion resistance is equally critical. Iron, the key element behind strong ferromagnetic properties, is also highly reactive…

Magnets are often listed with values such as surface Gauss, remanence (Br), and pull strength. While these terms are related, they describe different aspects of a magnet’s performance. Understanding their distinctions is critical for engineers, buyers, and anyone selecting magnets…

Permanent magnet materials must undergo rigorous testing to ensure their performance, consistency, and suitability for industrial applications. Several standardized methods exist to evaluate flux density, total flux, and magnetic hysteresis characteristics. Below is an overview of the most widely used…

Magnetizing direction plays a crucial role in determining how effectively a magnet performs in specific applications. While in some cases polarity may not matter, in many engineering and industrial uses, the magnetization orientation directly impacts performance, efficiency, and cost. Understanding…

When you see designations such as N35, N42, or N52, these numbers represent the grade of a neodymium magnet. The grade indicates the maximum energy product (BH)max, measured in MGOe, which reflects the strength of the magnet. Understanding these ratings…
