Abstract :
A hysteresigraph is developed based on two digital voltmeters to integrate the instantaneous electromotive forces induced in two independent search coils wound around the sample when the applied field is changed. The sensitivity of the equipment is 0.005 Tesla and the accuracy is better than 3%. A clear advantage of this system is its simplicity of set-up and usage, and the fact that the measurements are performed almost statically
