This device is electronic and used by researchers as well as students all over the world. If we have to analyze electrical signals we usually depend upon cathode ray oscilloscope. Physics researchers especially those who are carrying out magnetic materials research, rely on cathode ray oscilloscopes to draw magnetic hysteresis curves of feroomagnetic, antiferromagnetic and ferromagnetic materials. A pulse which is proportional to applied magnetic field and a pulse which is proportional to induced magnetic flux density or induced magnetization is fed to input of cathode ray oscilloscope. As a result of these we obtain a loop from which we can easily note down saturation magnetization value, Remanent magnetization value and coercive field.
