Magnets are awesome. Electromagnets are even cooler. But what if you could make a semi-permanent switchable magnet that acts like an electromagnet, but doesn’t use any energy to hold metal? You’re ...

Ohm's law and Kirchhoff's voltage law (KVL) provide powerful tools for conventional circuit analysis (mesh analysis), but if time-varying magnetic fields Ken Yang, Senior Member of the Technical Staff ...

Need a switch for small devices? Coto Technology claims that this switch fits in small spaces, works each time, and can be ...

Researchers have found that it is possible to make an electric circuit with a magnetic insulator. This was first deemed impossible. The circuit is realized using spin waves: wave-like perturbations in ...

These days when electronic circuits can be found almost anywhere, there is, some people fear*, a different kind of environmental pollution. They call it electrosmog (the word does not appear in any ...

They do not depend on temperature as a tripping mechanism, so they often find use where ambient temperatures are high. Their insensitivity to temperature also makes them candidates for protecting ...

A short circuit in one of the Large Hadron Collider's eight magnet sectors will delay the restart of the world's most powerful particle accelerator, Europe's CERN particle physics center announced ...

Because of an experience when I worked for GMC Truck and Coach 30 years ago, I have always thought thermal circuit breakers were not very good. Yet a recent experience with a thermal breaker seems to ...

The Federal Circuit breathed new life into an infringement suit against hard drive maker Seagate, saying the nine-year old ...
