INTRODUCTION

YGP-6230 hysteresis loop experiment is an experimental project specially used to measure the magnetic properties of magnetic materials. It mainly uses the electromagnetic induction method to determine the hysteresis loop, saturation magnetic induction intensity, coercive force and other parameters by measuring the magnetization characteristics of ferromagnetic materials under an external magnetic field. The hysteresis loop is the most obvious feature of ferromagnetic materials. According to the shape of the hysteresis loop, ferromagnetic materials can be divided into two categories: soft magnetic and hard magnetic. (The former has a long and narrow hysteresis loop, small coercive force, remanence and hysteresis loss; the latter has a wider hysteresis loop, large coercive force and strong remanent magnet).
