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 with moisture, making many high-performance magnets vulnerable to degradation if not properly protected.

Application principle of magnet in speedometer
The speedometer, or speed meter, is an instrument used to measure and display the instantaneous speed of a vehicle. It was first introduced in the early 1900s as an optional device and became standard equipment around 1910. Today, speedometers are universally installed in automobiles, motorcycles, and adapted for other vehicles such as boats (pit log) and aircraft (airspeed indicator).
Magnets play a key role in the functioning of traditional analog speedometers, making them accurate, durable, and reliable.

Difference between surface gauss, remanence and pull strength
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 for industrial or commercial applications.

How to choose the right magnetizing direction for different shapes of magnet?
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 the conventional and specialized magnetization options available helps engineers, designers, and buyers make the right decision.

How to Select Material Grades for Neodymium Magnets?
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.
- Higher numbers (e.g., N52) indicate stronger magnets at room temperature.
- Lower numbers (e.g., N35) are less powerful but more cost-effective.
Understanding these ratings is the first step in choosing the right magnet for your application.

How to Choose a Magnet for Fishing: A Complete Guide
Magnet fishing is an exciting outdoor activity that combines treasure hunting with environmental cleanup. Using a strong magnet attached to a rope, hobbyists and professionals can retrieve metallic objects from rivers, lakes, or other water bodies. It is often compared to underwater metal detecting but relies on the pulling force of magnets rather than electronic sensors.
For businesses, magnet fishing has also become a growing niche market—creating opportunities for supplying outdoor retailers, enthusiasts, and environmental groups with reliable magnet solutions.
