Dynamics of Nonsymmetric Conductor with Foucault’s Currents

Abstract

The purpose of this work is to measure the force acting on an asymmetric conductor in an alternating magnetic field. Since Foucault currents are inductive, the force acting on the conductor, averaged over the period of oscil-lations of the alternating magnetic field, must be equal to zero. This became the basis for making detailed meas-urements of the change in the weight of a conductor when a magnetic field is turned on. The nature of the magnet-ic field created by the source has been studied. This made it possible to determine the region where the magnetic field is uniform. Even when an unbalanced conductor is located in a region where the field is uniform, the aver-age force acting on the conductor is not zero. Particular attention is paid to the dependence of the change in the weight of the conductor in the form of a half ring on the angle of inclination with respect to the horizontal. This made it possible to separate the background component from the Abraham force, which is the force of the radia-tion reaction to the conductor. The maximum value of the measured Abraham force is significantly higher than the known experimental values and is observed with a horizontal conductor with a cylindrical surface located below
