In the early 1980s, the world witnessed a magnetic revolution that transformed industries ranging from automotive to renewable energy. At the heart of this revolution was the invention of neodymium-iron-boron (NdFeB) permanent magnets, a breakthrough that emerged from a cloak of corporate secrecy and competitive fervor.

A Tale of Magnetic Innovation

It’s a tale of innovation, competition, and simultaneous discovery that unfolded on opposite sides of the globe. General Motors (GM) in the United States and Sumitomo in Japan independently embarked on quests to develop a new generation of permanent magnets, unaware of each other’s efforts. Little did they know that their paths would converge in a surprising revelation at a conference in Pittsburgh in 1983.

 

The protagonists of this saga were Masato Sagawa of Sumitomo and John Croat of GM, leaders of their respective projects. Their pursuit was driven by the limitations of the existing magnetic technology of the time, namely samarium-cobalt magnets. While reliable and strong, samarium-cobalt magnets were prohibitively expensive, hindering their widespread adoption in various applications such as electric motors, generators, audio speakers, and hard-disk drives.

The Stage Was Set

With the stage set for innovation, both teams delved into the realm of rare earth metals, seeking to unlock the potential of neodymium, iron, and boron. Through rigorous experimentation and research, they stumbled upon a formula that promised unprecedented magnetic strength and efficiency.

 

The breakthrough came in the form of neodymium-iron-boron permanent magnets, offering a compelling combination of power, reliability, and cost-effectiveness. These magnets quickly became the cornerstone of modern technology, revolutionizing industries and enabling the realization of once-distant possibilities.

Demand Continues to Soar

Today, the legacy of Sagawa, Croat, and their teams lives on in the widespread adoption of NdFeB magnets. These magnets power the electric revolution, serving as vital components in electric vehicles, wind turbines, and countless other applications. As the automotive industry pivots towards electrification and renewable energy gains traction, the demand for NdFeB magnets continues to soar.

 

The market for NdFeB magnets is projected to surge to a staggering US $20 billion annually within the next few years, underscoring their indispensable role in shaping the future of technology and sustainability. From powering clean transportation to driving the renewable energy transition, these magnets are at the forefront of innovation and progress.

Apex Magnets

As we look towards the horizon of technological advancement, we can’t help but marvel at the magnetic forces that propel us towards a brighter, more sustainable future. The invention of neodymium-iron-boron permanent magnets stands as a testament to the power of human ingenuity and collaboration, transcending borders and corporate rivalries to redefine what’s possible.
