The Hysteresis Loop Tracer NV6108 is a versatile training system for the physics laboratories. This trainer is useful in understanding the basic concepts and fundamentals of hysteresis loss in ferromagnetic substances. A precise knowledge of various magnetic parameters of ferromagnetic substances, i.e coercivity, retentivity, saturation magnetization, hysteresis loss, and ability to determine these parameters accurately are important aspects of magnetic studies. The present set-up can accept the samples of different ferromagnetic substances and diameter. The demagnetization effects and different samples has been taken into account within the design. The equipment is complete in all aspects, including a set of samples.
