WebPositrons. The positron is an example of a particle with similar mass to an electron (~511KeV), but displaying "positive" rather than "negative" behaviour in response to an electric field. The observed difference in "charge" behaviour is expected to be due to a different electromagnetic field configuration compared to the electron.
