BH Curve Experiment

Objectives To observe and study the magnetization behaviour of the ferromagnetic magnetic materials provided. Principle The B-H curve is the curve characteristic of the magnetic properties of a material or element or alloy. It tells you how the material responds to an external magnetic field, and is a critical piece of information when designing magnetic circuits. A Ferromagnetic material, retains its magnetization even after the external magnetic field is removed. And the reversal or change in the direction of the applied external magnetic field results in a change in the magnetization of the ferromagnetic material. It is seen that the change in the magnetization lags behind the change in the applied external magnetic field. Thereby, a hysteresis behaviour is exhibited. Key Features Compact Setup – The apparatus design is compact and yet effective to perform the experiments with ease. The simple connections and stand to hold the teslameter probe, makes it easy to handle. Multiple samples included – Multiple ferromagnetic samples are provided to study the BH curves of the different materials. The removable cores make it easy to change between samples.
