China is the world’s biggest producer of rare earth magnets, with the United States military being one of its most significant consumers. Historically, the U.S. has spent enormous sums in order to remain the world leader in military technology and ensure a strong presence on the global stage.   The military commonly uses neodymium and samarium-cobalt, while both very strong, they each come with their own unique advantages and disadvantages. For instance, neodymium provides the highest power-to-weight ratio, but neodymium magnets are brittle and have relatively low heat resistance. Samarium-cobalt, while also brittle and more expensive, provides heat resistance and a high level of corrosion resistance.  Magnets and the Military So, how does the military make use of magnets? The demand starts somewhere familiar –– compasses. Distributed to new recruits, compasses are used on the ground and in cockpits to check direction at any given moment. The focus on technological breakthroughs, however, means that the armed forces employ magnets for much more than just navigation.  Each branch requires the latest in computer tech. This creates a demand for hard drive magnets in aircrafts, tanks, and command centers –– with magnets being critical in communication systems like speakers and microphones. In addition to compasses and computers, there are several other ways the military uses magnets.  Magnetic Sweepers Just as warehouses need to keep their shop floors clear of stray nails and screws, military bases need to keep their runways free of anything that could pop or damage aircraft tires. Something as simple as a nail could halt an entire operation. A similar kind of magnetic floor sweepers are available for industrial purposes as well. Holding Gear and Powering Devices Taking a cue from magnetic laptop power cables, some soldiers use magnets to securely attach gear to their uniforms. These magnets even help power some of their electronics. Since the connections are magnetic, users can make attachments single-handedly, often without looking down, allowing them to stay alert to their surroundings. Transportation Since magnets are crucial in electric drive motors, neodymium and samarium-cobalt are crucial in applications like Combat Hybrid Power Systems, the electric drive in the enormous Zumwalt DDG 1000, and various electronic aircrafts.  Attack Systems Rare earth magnets are used in a variety of attack methods like the fin actuators used to guide missiles in mid-air. Back on land, magnets are commonly used for the detection and detonation of mines.
