- Construction Giant L&T Said to Plan India Rare-Earth Magnet Bid
Larsen & Toubro Ltd. plans to manufacture rare-earth magnets in India. This initiative aligns with a government effort designed to reduce the nation's reliance on imports. The goal is specifically aimed at loosening China’s control over this critical industrial component.
- ‘Virtual magnet’ claims reveal why EVs need their rare-earth magnets
Efforts to replace permanent magnets in electric vehicle (EV) rotors with electromagnets or iron face challenges related to efficiency, starting torque, and maximum speed, which limit their adoption in EVs. The article highlights the importance of rare-earth magnets in EVs due to these technical constraints.
- China Is Exporting 20% Fewer Magnets to US Despite Trade Truce
China’s shipments of rare-earth magnets to the US have dropped by 20% compared to pre-trade war levels, despite a trade truce. The Trump administration has raised concerns about China’s compliance with the agreement.
- McKinsey chairs: Building a more resilient industrial base may require $2 trillion in investment
McKinsey highlights the need for a $2 trillion investment to rebuild the U.S. industrial base, driven by geopolitical risks and technological competition. The U.S. imports $3 trillion in manufactured goods annually, with critical vulnerabilities in products like semiconductors, data center servers, and rare-earth magnets due to supplier concentration and geopolitical distance.
- China’s grip on rare-earth magnets could crush US drone industry before it grows
China's dominance in rare-earth magnet production threatens the U.S. drone industry's ability to scale manufacturing, as these magnets are critical for drone motors. The Pentagon's Drone Dominance Program aims to purchase 340,000 drones by 2028 but faces supply chain challenges due to reliance on Chinese imports. Alternatives like iron nitride magnets are highlighted as potential solutions.
