In a recent work, we calculated the magnetic field inside a free electron due to its spin, and found it to be about B = 8.3 × 10 13 T. In the present study we calculate the spinning speed of a free electron in the current loop model. We show that spinning speed is equal to the speed of light. Therefore it is shown that if electron was not spinning the mass of electron would be zero. But since spinning is an unseparable part of an electron, we say that mass of electron is non-zero and is equal to (m = 9.11 × 10 −28 g).

The current loop model is mainly based on the magnetic top model which was first introduced by Barut et al. [9] and used by N. Rosen [10] and L. Schulman [11]. But the magnetic top model was rather primitive as the spin vector was only attached
Lifetimes of the first excited-state of sodium dimers are measured using time-resolved spectroscopy. Molecular fluorescence decay-time was recorded using time-correlated photon-counting technique and lifetime was extracted using a Stern-Volmer plot.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
