During normal operation, thermal circuit breakers utilize a thermal sensing element (such as bimetal), which deflects when the temperature reaches a predetermined calibration level, causing the ...

On April 1—no joke—the Consumer Product Safety Commission’s troubling new standard for magnet sets was slated to go into effect. However, thanks to the efforts of the sole remaining distributor of ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
