The induction law in relativistic mechanics

It is shown that both parts of the law of induction, i.e., the 'static' induction and the induction caused by movement can be derived and satisfactorily proved in a relatively clear manner with a slight mathematical error by using the special theory of relativity. The magnetic field is introduced by means of Biot-Savart's law, i.e., as a phenomenon associated with electric fields which are also moving. The selected form of presentation permits the illustration of the phenomena associated with the induction of electric fields, which is for the students sometimes difficult to understand.
