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 ...

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 ...

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 ...

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 ...

Magnetic fields may play a bigger role in neutron star mergers than previously thought. A new study using advanced simulations shows that these fields can shift or suppress oscillation frequencies, ...

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 ...
