A research group from the Graduate School of Engineering at Tohoku University has developed a noninvasive means of detecting ...

Today's computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to ...

We’re probably all familiar with the Hall Effect, at least to the extent that it can be used to make solid-state sensors for magnetic fields. It’s a cool bit of applied physics, but there are other ...

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. Researchers have developed a light-based technique ...

The human body is controlled by electrical impulses in the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various ...

The ACS37100 is available in an industry-standard SOICW-16 package that supports a working reinforced isolation up to 565 V ...

Tiny deviations: the new metal detector looks for minute disturbances in Earth’s magnetic field. (Courtesy: iStock/muffinmaker) A compact, low-cost and low-power metal detector that can identify the ...
