It looked still to you before because you were moving with it. We have this same problem with electric and magnetic fields. Depending on your reference frame, what appears to be a magnetic force ...

This paper discusses the magnetic measurements of residual field in superconducting dipole and quadrupole magnets. The technique used to measure residual fields is described herein. The results of the ...

While Earth’s magnetic field resembles a bar magnet neatly aligned with its axis, these planets generate wonky, off-center fields that seemingly defy explanation, until now. A Berkeley physicist has ...

Abstract: Three-axis magnetometers (TAMs) provide rich measurement information and are widely used in magnetic target detection, geological measurement, geomagnetic navigation, and other fields. The ...
