BH Curve Ferromagnetic Hysteresis Experiment Set Up

The B-H Curve Measuring Apparatus is designed to observe and study the magnetization behavior of ferromagnetic materials. It enables students to analyze the relationship between magnetic field strength (H) and magnetic flux density (B), demonstrating the hysteresis characteristics of ferromagnetic materials. The apparatus provides a compact and efficient setup for understanding magnetic properties and comparing the behavior of different magnetic samples. Manufactured by Atico Export India.

Principle

The B-H curve represents the magnetic characteristics of a material and illustrates its response to an external magnetic field. Ferromagnetic materials retain their magnetization even after the external magnetic field is removed. When the direction of the applied magnetic field is reversed, the magnetization of the material changes with a delay, resulting in a hysteresis loop. This behavior is essential for understanding the magnetic properties of ferromagnetic materials and the design of magnetic circuits.
