Experimental setup for studying the motion of a body in a central force field

Abstract

The article presents the main stages of creating an experimental setup for studying the motion of a body in the
field of central attraction. This force is analogous to the central gravitational force. The electrical diagram of the installation is described in detail. This circuit produces a rectified pulsating current. This current in turn generates a magnetic field in a vertically positioned coil. The authorshave investigated the magnetic force of the coil acting on an iron object. This object is located on the horizontal plane of the upper part of the coil.
There is presented theoretical conclusion of Robert Wood about the value of the horizontal component of the magnetic intensity of a vertically arranged coil with a current. This value is inversely proportional to the square of the distance from the center of the upper part of the coil. The magnetic force also varies inversely with the square of the distance. On the basis of these theoretical calculations, there have been constructed an experimental setup. This setup demonstratesthe movement of the body in the field of the central force. The trajectory of the metal ball has been experimentally tested. These trajectories correspond to conic sections on the horizontal plane of the fiberglass.
