Electrons' magnetic interactions measured
By Ashley Yeager, 18:16 PM June 19, 2014
The minuscule magnetic interaction between two electrons has been measured.
Electrons can act as tiny bar magnets and exert a magnetic force on each other. The strength of this minuscule magnetic interaction has been hard to measure. But by cashing in on characteristics of quantum mechanics, a team was able to show that the strength of the interaction depends on the distance — specifically, 1 divided by the distance cubed — between the two particles.
The results, reported in the June 19 Nature,...
