Suppose you are concentrating on a small cross-section in space nearby that electron. Thus when that electron moves the electric field throught that cross-section changes.
This fluctuating electric field generates a magnetic field.
This is in accordance to the maxwell's equations. For proper theory, knowledge of relativity is required and is of much higher level
