The magnetic moment of a magnet is a quantity that determines the torque it will experience in an external magnetic field. A loop of electric current, a bar magnet, an electron (revolving around ...

When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at Brookhaven National Laboratory discovered something ...

A new estimation of the strength of the magnetic field around the muon -- a sub-atomic particle similar to, but heavier than, an electron -- closes the gap between theory and experimental measurements ...

IT is well known that the magnetic moment of the proton and the neutron cannot be explained by Dirac's relativistic wave equation. It was first suggested by Wick 1 that the surplus moment of the ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...
