Electron Diffraction Experiment Disturbed by Magnetic Field

Abstract

The Copenhagen interpretation of quantum mechanics holds that as long as electron diffraction fringes are monitored, they will vanish.  For a long time, no scientific papers have been published on the "electron diffraction experiment monitored by a magnetic field" (there are only popular science reports in this area). In order to verify the authenticity and inevitability of quantum state superposition and wave function collapse, electron diffraction experiments under the interference of permanent magnets were carried out. As a result, the electron diffraction fringes can be deformed and drifted by the magnetic field interference, but they will not vanish. It is apparent that measurement interference cannot cause wave-particle duality particles to collapse into whole particles. In quantum physics, this is an experimental counterexample (also a dark cloud over quantum mechanics).  Both "the existence of the superposition of quantum states" and "the superposition of quantum states cannot withstand any observation and surveillance" are questionable.
