A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation ...

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 ...

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 ...

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 ...

Human neuroimaging Researchers in Massachusetts are developing a human brain-scale MPI scanner with a mechanically rotated, permanent magnet-based field-free line. (Courtesy: Lawrence Wald) Magnetic ...

Yes, it will create an image of field lines coming out of a magnet, but it’s a very slow process. Instead of using just one magnetic sensor, [Peter] is building a two-dimensional array of ...

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 ...
