Investigation of the motion of a magnet along conductive inclined plane by means of a robotic set

摘要

Abstract The article presents the results of an experimental study on the motion of a neodymium magnet on an inclined duralumin plate. During experiments, the time of motion was measured, and the steady-state velocity of the magnet motion was determined. To measure the time, a robotic set was used, which made it possible to measure the time of the motion with an accuracy of 0.001 s. It is demonstrated that the velocity of the motion of a magnet in the case when its direction is perpendicular to the magnetic moment (vector directed from the south pole of the magnet to the north) and both vectors lie in the plane parallel to the plate is 3.3 times larger than in the case when these vectors are parallel. The article gives a qualitative explanation of this phenomenon. In the non-stationary formulation, the problem of the motion of a conductor in a homogeneous magnetic field is solved. It is demonstrated that in the approximation when the self-induction effects can be neglected, the solution has the self-similarity property (that is, the solution contains no parameters other than the variable coordinate and time). The dependence of the coordinate of the conductor on the travel time turned out to be similar to that for a magnet.
