Electric vehicle manufacturers are in a bind: embrace a rare earth magnet market projected to explode to $11.3 billion by 2032, or gamble on AI-designed alternatives that might never deliver.

• The global rare earth magnet market for electric vehicles, valued at $2.5 billion in 2023, is projected to reach $11.3 billion by 2032, prompting exploration of AI-designed alternatives.
• IDTechEx reports that rare earth permanent magnet motors have maintained over 75% market share since 2015, despite concerns over supply chains and ethical sourcing.
• Car manufacturers and suppliers need to actively invest in and validate AI-designed magnet alternatives now to diversify their supply chains and potentially reduce reliance on ethically questionable rare earth sources.

The $11.3 Billion Gamble: Can AI Break the Rare Earth Magnet Monopoly?

The electric vehicle (EV) permanent magnet market is not just growing; it’s on a trajectory to redefine the automotive landscape. Projections estimate the global market reaching $13.4 billion by 2025. This surge is primarily fueled by the insatiable demand for high-performance magnets in EV motors, a demand currently met almost exclusively by rare earth elements (REEs). However, this dependence comes with its own set of risks. The price volatility, ethical sourcing concerns, and geopolitical vulnerabilities associated with REEs are forcing manufacturers to explore uncharted territories, with AI-designed magnets emerging as a potential, albeit high-stakes, solution. The question is: can algorithms truly replace geological fortune?

The promise of AI in magnet design lies in its ability to sift through vast datasets, identifying novel material combinations and microstructures that could replicate or even surpass the performance of existing rare earth magnets. This isn’t just about finding alternatives; it’s about creating magnets with tailored properties, optimized for specific EV motor designs and operating conditions. Yasuke Sasaki, a principal researcher at the Institute for Materials Science and Technology in Japan, believes AI holds the key to unlocking this potential.

We found that by using AI, the performance of magnets can be improved with a small number of experiments.

This implies a future where magnet design is less about laborious trial and error and more about intelligent prediction and optimization, potentially shortening development cycles and reducing material waste. The industry is keenly aware of this potential, with both established magnet manufacturers and emerging tech companies vying to stake their claim in the AI-driven magnet revolution.

China’s 90% Grip: Why the EV Industry Feels Trapped, according to MIT Technology Review

The electric vehicle industry’s reliance on rare earth magnets is not merely a technological preference; it’s a strategic vulnerability, exacerbated by the near-monopolistic control China exerts over the rare earth supply chain. China accounts for approximately 60% of global mining of magnet rare earths, over 90% of rare-earth separation and refining, and over 90% of sintered NdFeB magnet manufacturing in 2024. This dominance allows China to dictate prices, control supply, and potentially weaponize rare earth exports for geopolitical leverage.

This stranglehold leaves EV manufacturers feeling trapped, beholden to a single source for a critical component. The industry narrative, often amplified by corporate PR, downplays the severity of this dependence, painting it as a manageable risk. The reality, however, is far more precarious. Any disruption to the Chinese rare earth supply, whether due to trade tensions, environmental regulations, or unforeseen geopolitical events, could send shockwaves through the EV industry, crippling production and driving up costs. This isn’t a hypothetical scenario; it’s a Sword of Damocles hanging over the entire sector.

The situation is so critical that Daniel Pickard, chairman of the critical minerals advisory committee for the Office of the United States Trade Representative and the Department of Commerce, stated: “A swift resolution of the rare earths issue is necessary because a sustained disruption of exports could hurt China’s reputation as a reliable supplier”. The fact that a U.S. government official is concerned about China’s reputation should speak volumes about the imbalance of power at play.

The Ferrite Fallacy: Why Cheaper Isn’t Always Better for Tesla and Ford

The industry consensus often proposes ferrite magnets as a viable, cost-effective alternative to rare earth magnets. While ferrites are indeed cheaper and more readily available, they suffer from a significant performance deficit. The problem is physics. Ferrite magnets have a much lower energy product than NdFeB magnets, meaning they produce a weaker magnetic field for a given size and weight. This translates to lower motor efficiency, reduced torque, and ultimately, compromised vehicle performance.

Replacing NdFeB magnets with ferrite magnets would be akin to downgrading a Ferrari engine to that of a Ford Fiesta – cheaper, yes, but hardly desirable. The pursuit of cost savings shouldn’t come at the expense of performance, especially in a market where consumers are increasingly demanding high-performance EVs. This is the fallacy at the heart of the ferrite argument: it prioritizes short-term cost reduction over long-term performance and brand reputation.

Kartik Ganesh, principal at IDTechEx, highlights a different direction: “Recently, OEMs have been actively investigating EESM motors as a viable alternative to PMSM motors permanent magnet synchronous motors, as EESMs mitigate the risks linked to REEs. Additionally, more suppliers are beginning to develop EESMs to meet this growing demand”. This suggests that the smart money is betting on a more innovative approach, one that doesn’t simply trade performance for price.

Dysprosium’s Dilemma: Temperature Sensitivity and the Hidden Costs of Neodymium Magnets

Even within the realm of rare earth magnets, there lurks a hidden vulnerability: temperature sensitivity. Neodymium magnets, while boasting exceptional strength, can lose their magnetism at elevated temperatures, a critical concern for EV motors that generate substantial heat during operation. The solution? Add heavy rare earth elements like dysprosium and terbium. These elements act as thermal stabilizers, preventing the magnets from demagnetizing at high temperatures. However, dysprosium and terbium are even rarer and more expensive than neodymium, further complicating the supply chain and driving up costs. This reliance on heavy rare earths creates a “dilemma within a dilemma”.

The industry often downplays this issue, framing it as a minor technical challenge easily overcome with existing solutions. The reality is that the addition of dysprosium and terbium adds significant cost and complexity to magnet production. Furthermore, the mining and processing of these heavy rare earths carry even greater environmental and ethical concerns than those associated with neodymium. This is the hidden cost of neodymium magnets: a Faustian bargain where performance is maintained at the expense of increased environmental impact and supply chain vulnerability.

From Lab to Line: Will AI-Designed Magnets Actually Power Tomorrow’s EVs?

The question is whether AI-designed magnets can make the leap from laboratory curiosity to mass-produced, high-performance components in tomorrow’s EVs. The global electric vehicle (EV) permanent magnet market is projected to reach $13.4 billion by 2025, and capturing even a fraction of that market would require a radical transformation in magnet manufacturing.

Current AI efforts are largely focused on discovering novel material combinations and optimizing magnet microstructures. These are promising avenues, but significant challenges remain. Scaling up production of these new materials to meet automotive demand will require substantial investment in new manufacturing processes and equipment. Furthermore, the long-term durability and performance of AI-designed magnets in real-world EV operating conditions remains largely untested. Overcoming these hurdles will require close collaboration between research institutions, magnet manufacturers, and automotive OEMs.

The Bottom Line

AI-designed magnets offer a vital, albeit long-term, pathway to mitigating risk and ethical concerns in the EV magnet supply chain. Automakers should directly fund and partner with research institutions like the University of New Hampshire to accelerate the development and testing of AI-designed magnet alternatives. Rare earths are on notice.
