Hysteresis Curve & Magnetization Measurement Equipment for Magnetic Materials
DESCRIPTION / TECHNICAL SPECIFICATIONS
Introducing a practical and significant experimental system designed to investigate the basic characteristics of magnetic material namely the hysteresis loop and the initial magnetization curve This apparatus is a major upgrade compared to traditional methods like the ballistic galvanometer and is specifically designed to provide a deep understanding of ferromagnetism a crucial topic in applied physics materials science and various industrial applications
The primary function of this device is to allow students to accurately map the magnetic response of a material They can measure the initial magnetization curve by gradually increasing the current using the continuously adjustable digital current source and simultaneously measure the resulting magnetic induction (B) using the high-accuracy digital teslameter equipped with a Hall sensor
Upon reaching saturation students can then trace the entire hysteresis loop by varying the current forwards and backwards This process allows for the determination of crucial material parameters such as remanence the residual magnetization at zero external field and coercivity the reverse field required to demagnetize the material Additionally the device features an integrated demagnetization function which is not only useful for sample preparation but also teaches a basic concept of DC magnetism
A unique feature of this instrument is its ability to create a micro parallel gap in the rectangular sample This allows students to measure the magnetic induction distribution within the gap and then use that data to calculate the magnetic field strength (H) an excellent practical application for deepening the understanding of Ampere's Law
With an all-in-one design housed in a sturdy portable case this apparatus offers a complete and convenient solution for the teaching laboratory Equipped with clear digital displays for both current and magnetic field as well as prepared samples it is an indispensable tool for physics experiments in universities and colleges making the complex topic of ferromagnetism more accessible and experimentally verifiable
