Homemade kit for demonstrating Barkhausen Effect

Abstract

This paper presents an innovative and cost-effective approach to understanding the Barkhausen effect through the design and implementation of an educational kit. The Barkhausen effect, characterized by Barkhausen noise (BN) during magnetization changes in soft magnetic materials, is explored for its application in probing hysteresis properties and magnetization dynamics. The study investigates scaling properties, categorizing ferromagnetic materials based on scaling exponents. The primary contribution is the introduction of a practical and accessible kit for hands-on Barkhausen Effect demonstrations, revolutionizing the educational experience. This kit enables students to not only comprehend the intricacies of BN but also calculate the scaling constant ($\tau$) for Soft Iron samples. The paper demonstrates the successful construction of the kit, its signal amplification capabilities, and data collection accuracy, showcasing its potential for widespread educational use.
