Induction of the field at different distances from the permanent magnet and between opposing magnets. Testing of the superposition principle

Abstract

The measurement data of the field induction at different distances from the permanent magnet Nd-Fe-B and between two equivalent magnets on distance are presented. It is shown that the obtained coordinate dependences are described by exponential function, but for a system of two magnets -only partially: up to the central area of the system and make 20-30% of the entire area between opposing magnets. Using the example of the coordinate dependence of induction for one of two identical magnets, it is shown that the use of the superposition principle makes it possible to obtain a coordinate dependence of induction between opposing magnets, which is equivalent to experimental one.
