Magnetic Hysteresis Loop Tracer

Hysteresis Loop tracer enables the user to determine accurately various magnetic parameters of ferromagnetic substances, viz. coercivity,
retentivity, saturation magnetisation and hysteresis loss.

The present set-up can accept the samples of thin wires of different diameters. The demagnetisation
effects, different diameters of samples and eddy currents (due to the conducting property of the material) has been taken into account within the design or graphically.

Applications

The following magnetic parameters can be measured by this set-up:
 - Coercivity

 - Retentivity

 - Saturation magnetisation

 - Various magnetic phase identification

 - Hysteresis loss

The set-up is complete in all respect, including long solenoid, its power supply with a panel meter directly calibrated in gauss, sample holder with a pick-up coil and a set of samples: hard steel, soft iron and nickel (all in wire form.). A Cathode Ray Oscilloscope will however be required.
