We break down the differences between moving coil and moving magnet phono cartridges. The vast majority of turntables sold in 2022 come with a pre-installed phono cartridge. Most consumers are ...

Discover how to build a simple electric train using just a copper coil, an AA battery, and disc magnets in this step-by-step science experiment. Starting with basic materials, watch as we construct ...

Moving-magnet or moving-coil cartridge? For the in-betweens, Goldring today introduced the Eroica HX high-output moving coil cartridge, which offers a taste of moving-coil sound without the additional ...

The D’Onghia magnetic shielding crew hat, or CREW HaT, is a system that uses electromagnetic coils to deflect cosmic radiation from astronauts. The system consists of: A ring of electrical coils ...

We admit that this project doesn’t have very many details available, but it was just too neat for us to pass up. It’s a small linear motor which [ligonapProduktion] built after seeing a very brief ...

If you drop strong magnets onto a plate of copper, something remarkable happens: the magnets slow down before hitting the surface and appear to levitate slightly, like the copper is another magnet, ...

KEARNY, N.J., March 20, 2025 (GLOBE NEWSWIRE) -- Thea Energy, Inc., a fusion technology company advancing the stellarator for the commercialization of a carbon-free and abundant source of energy, ...

Why magnets sit at the heart of fusion’s next leap Magnetic confinement is the central engineering challenge for fusion power because the fuel must be heated to temperatures hotter than the core of ...

Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez] demonstrates ...
