Exploring the specific charge of an electron, this fundamental physics concept denotes the charge-to-mass ratio of an electron, crucial for understanding its behavior in electric and magnetic fields. Historical milestones include J.J. Thomson's cathode ray experiments and Robert Millikan's oil drop experiment, which collectively led to the precise calculation of the electron's mass and charge. The specific charge is vital in technologies like MRI and electron microscopes, and in explaining natural phenomena such as auroras and lightning.
