Everyone interested in electronics should build at least one Tesla coil. But be careful. Sure, the high voltage can be dangerous, but the urge to build lots of coils is even worse. [Learnelectronics] ...

Tesla coils are one of those builds that capture the interest of almost anybody passing by. For the naïve constructor, they look simple enough, but they can be finicky beasts—beasts that can bite if ...

Researchers at ETH Zürich have built the most powerful miniature superconducting magnets ever demonstrated, potentially opening the door to affordable, lab-scale high-field science. Generating ...
