Universal B-H Curve Tracer
We have developed technique to quickly trace B-H loop of ferromagnetic materials of any shape without winding primary and secondary coil on the sample. The present technique is specially designed for teaching and industrial applications. Universal B-H Curve Tracer is a self contained instrument and need any low cost C.R.O having X-Y gain. In this technique, B-H loop is formed by simply inserting the specimen in a magnetizing coil. It make use of a specially designed
integrated circuit probe to measure the flux density B. Any magnetic specimen, e.g. a 4-inch nail, soft iron wire or a hacksaw blade can be inserted in a magnetizing coil without disturbing the arrangement. Change of the specimen results in a different shape of the hysteresis Curve. Even 10MHz CRO is sufficient for the B-H Loop.
