The Birth of Magnetism
Ancient Discoveries
Long ago, people found lodestone. This natural magnet was used in Greece and China . It helped sailors with compass navigation in the Song Dynasty .
Renaissance Revolution
In 1600, William Gilbert wrote De Magnete. He said Earth is a big magnet . This was the start of modern magnetism.
The Rise of Permanent Magnets
Alnico and Ferrite Magnets
In the 1930s, Alnico alloys were made. They worked well in motors and radios. Later, ferrite magnets became popular for speakers and toys .
The NdFeB Revolution
In the 1980s, NdFeB magnets were invented. They are the strongest magnets ever made .
Modern Innovations Powered by NdFeB Magnets
Renewable Energy
Wind turbines use NdFeB magnets to make power. They work better and last longer . We make custom magnets for wind turbines that endure harsh conditions.
Electric Vehicles (EVs)
Tesla’s Model 3 uses NdFeB magnets in its motor. These magnets help cars go farther on a charge . Our NdFeB for the automotive industry is trusted worldwide.
Medical Technology
MRI machines use NdFeB magnets for clear scans. They are lighter and more efficient . We supply medical-grade magnets with ISO 13485 standards.
How to Choose the Right Permanent Magnet
Understand Your Needs
Think about size, strength, and heat resistance. For example, N42H magnets work well in high heat.
Compare Materials
NdFeB magnets are the strongest. Ferrite is cheaper but weaker.
