World’s strongest resistive magnet fired up in China

Scientists in China have developed the world’s strongest resistive magnet, which produced a steady magnetic field of 42 Tesla (T). The system could improve devices that use magnets, as well as enable a range of new experiments that probe electromagneti… Continue reading World’s strongest resistive magnet fired up in China

Launching Model Airplanes With a Custom Linear Induction Motor

Launching things with electromagnetism is pretty fun, with linear induction motors being a popular design that finds use from everywhere in hobby designs like [Tom Stanton]’s to the electromagnetic launchers …read more Continue reading Launching Model Airplanes With a Custom Linear Induction Motor

Nanomaterial stimulates and regrows severed nerves like sci-fi tech

In a move that echoes a sci-fi series, researchers have developed a super-small material that was able to not only stimulate nerves in rodents, but reconnect them as well. The finding could lead to injectable particles that take the place of larger imp… Continue reading Nanomaterial stimulates and regrows severed nerves like sci-fi tech

DARPA launches program in quest for “Red October” silent submarine drive

Taking a plot point from the 1990 Sean Connery thriller The Hunt for Red October, DARPA is working on a super-silent submarine drive that has no moving parts and provides propulsion through the water using magnets and electricity.Continue ReadingCatego… Continue reading DARPA launches program in quest for “Red October” silent submarine drive

Experimental “Faraday fabric” blocks almost all electromagnetic waves

Researchers at Drexel University have created “Faraday fabrics” that can block almost all electromagnetic waves. The key ingredient is a 2D material called MXene, and the development could help protect wearables from interference and people from potent… Continue reading Experimental “Faraday fabric” blocks almost all electromagnetic waves

“Remote control” for diabetes tackles blood sugar with electromagnetism

For many type 2 diabetics, keeping blood sugar to healthy levels is a painstaking task involving regular monitoring and insulin injections, but scientists are pursuing more convenient ways to manage the condition. Among them is a research group at the … Continue reading “Remote control” for diabetes tackles blood sugar with electromagnetism

2D material absorbs electromagnetic waves for superior shielding

Electromagnetic interference can be a serious problem for electronic devices, so shielding is usually placed around components. Now, engineers at Drexel University have found that a 2D material called titanium carbonitride is an excellent shielding mat… Continue reading 2D material absorbs electromagnetic waves for superior shielding
