A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation of magnetic fields using what may be the tiniest compasses around—atoms.

In response to a changing magnetic field, so-called alpha brainwaves, the background “hum” of the brain, quieted in human volunteers, scientists reported yesterday (March 18) in eNeuro. “This is the ...

Researchers at the University of Colorado Boulder (CU Boulder) have made a significant advance in magnetic ... of the human brain. However, accurately measuring the direction of these fields is ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM ...

or specific cartesian components of the magnetic field. Although knowing all three vector components of a field provides more complete information about it, a truly scalar sensor has an advantage ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...
