Abstract
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 × 1013 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).

Summary
We have calculated the magnetic field inside a free electron due to spinning motion [1] and showed that it is about 8.3 × 1013 T. To overcome this difficulty we introduced current loop model [6]. In this study using the current loop model we have found that: electron’s spinning angular frequency, = ωs 7.77 ×1022 rad sec Most importantly through this model we had calculated magnetic flux associated with its spinning motion and we have found the above mentioned result: Φ(es) = ± hc 2e = ± Φ0 2 where (+) sign stands for spin-down electron and (−). Since spinning is an unseperable part of electron we may say that mass of electron is non-zero and is equal to 9.11 × 10−28g
