  Stern-Gerlach experiment by free electron is very important experiment
because it answered some questions that remain unanswered for almost a century.
Bohr and Pauli considered its objective observation as impossible while some
other scientists considered such observation as possible. The experiment on
free electrons has not been conducted so far because the high magnetic field
gradient predicted there was thought as impossible to generate. This paper
proves that it is not only possible but also observable using a high vacuum
lamp which is deionized well. To obtain a high magnetic field gradient, it is
not necessary to have a very strong magnetic field and it is possible to
observe the phenomenon using a very sharp pointed magnet and adjusting the
voltage in a certain distance from free electron beams. that objective
observation requires your consideration of some technical points
simultaneously.In this experiment, no electric field and no magnetic field does
not change with time.
