Scientists have developed a sensor for measuring the strength of electric fields, which is much smaller, simpler and less prone to distortion than comparable devices.

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Low-intensity electric fields can disrupt the division of cancer cells and slow the growth of brain tumors, suggest laboratory experiments and a small human trial, raising hopes that electric ...

Medical devicemakers are tapping into electric fields as a new treatment for cancer, The Wall Street Journal reported May 16. For decades, electricity has been used to treat cardiovascular ...

There’s a magnetic field and you need to measure its strength. But how? Here are some options. Magnetic Compass Back when I was a kid, we had these things called compasses. It’s just a ...
