The Novelties by Using R Programming Language for Simulate Magnetic Hysteresis Loop

Abstract

Magnetic materials can be classified as hard and soft, depending on the shape of the hysteresis loop. The hysteresis loop describes the magnetic behaviour of the magnetic materials to which an external magnetic field is applied. The shape of the hysteresis loop can be obtained by drawing point by point the B-H dependency by measuring the induced magnetic flux density (B) and the magnetizing force (H), or by visualization with specific laboratory equipment (usually the oscilloscope). Because of the labouring process of these experiments and due to the little research in the computational methods in this direction, nowadays it is impossible to find data sets with a hysteresis loop that can be further used for automatic classification of the magnetic materials and automatic detection of the magnetic materials application field. This paper aims to create and generate the magnetic hysteresis loop in the R programming language with two different approaches. One model was created with a hysteresis package, and one was created by using a synthetic function cloned with an existing mathematical model for magnetic hysteresis.
