In a world filled with high-tech robotics kits and programmable gadgets, one artist decided ...

While electric vehicles certainly offer a host of eco-friendly advantages, they're not without some asterisks, one being the rare earth materials (and harmful mining thereof) used to make the magnets ...

Inventors and fans have long been captivated by the concept of a magnetic engine, which uses magnets to create perpetual motion and power a vehicle without the need for fuel. Nevertheless, it is still ...

Permanent Magnet AC motors hold the largest market share because they are more efficient, have a higher torque-to-weight ratio, and perform better in variable speed applications than other motors.

The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...

With its Hunstable Electric Turbine, Linear Labs promises three times the torque, twice the power and a 10% increase in range in an electric vehicle over a typical permanent magnet motor. One problem ...

The switch to a neodymium-intensive permanent magnet motor in a volume model like the Model 3 has some worried about long-term supply issues. Kyle Hyatt (he/him/his) hails originally from the Pacific ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws of ...

"The market has gone absolutely crazy." That's the shared sentiment among many executives at magnetic material and motor plants. As of February 9, 2026, the price of praseodymium-neodymium (Pr-Nd) ...
