With the rapid spread of cloud computing, artificial intelligence and data centers, global energy consumption is rising to ...

Controlling magnetism in a device is not easy; unusually large magnetic fields or lots of electricity are needed, which are bulky, slow, expensive and/or waste energy. But that looks soon to change, ...

[Stoppi] always has exciting projects and, as you can see in the video below, the latest one is a very simple magnetic levitator design. The design is classic and simple: a 5 V regulator IC, a Hall ...

Electric fields can reliably reverse magnetization in nanoscale structures of the multiferroic material BiFe0.9Co0.1O3 (BFCO) ...

Permanent magnets aren’t typically switchable. They’re always doing their magnet thing. However, if you align them with a bunch of other magnets in just the right way, you can create a permanent ...

Cuktech’s 10,000mAh magnetic power bank offers the best of both worlds: wireless charging and fast wired charging. Its lightweight design makes it easy to carry — and its tiny price tag makes it a ...

How quantized electrical transport works Many people will probably still remember the classical Hall effect from their physics lessons: When a current flows through a conductor exposed to a magnetic ...

In 1824, an English engineer invented the first working electromagnet laying the foundation for modern electrical engineering ...
