Experiment to Prove the Existence of the Advanced Wave and Experiment to Prove the Wrong Definition of Magnetic Field in Maxwell’s Theory

Abstract

Experiments were proposed using classical methods to generate advanced waves and send signals from the current to the past. The experimental methods are to change the impedance of the load and then measure the change in the output power of the power supply. According to the mutual energy theorem, the load will absorb energy from the power supply through advanced waves or advanced potentials, and the change in power supply should occur before the load changes. Therefore, it is possible to send the signal to the past. Communication from current time to the past time should be possible. This article will use three experiments to test it. These experiments are classic experiments that do not use quantum entanglement effects. This article also introduces the magnetic field measurement method using the Hall effect to measure the magnetic field of electromagnetic waves. According to the author's electromagnetic theory: mutual energy theory, the magnetic and electric fields of electromagnetic waves have a phase difference of 90 degrees. According to Maxwell's electromagnetic theory, the phase of the magnetic field and electric field is 0 degrees. The correctness of the two theories can be judged by Hall effect magnetic field measuring instruments. However, measuring instruments with high sensitivity and corresponding high frequency are required. If the phase difference between the magnetic field and electric field of an electromagnetic wave is 90 degrees, it indicates that the author's electromagnetic theory is correct, which can indirectly prove the existence of advanced waves.
