Principle and Working:
A Magnetic field is generated in a U & I shape iron core by continuous (Sin or Triangular) wave to primary coil which generates the magnetic field strength H as
Where L: Effective length of iron core, N1:Number of turn.
The corresponding magnetic induction B is obtained through integration of the voltage V induced in second coil as:
Where A: Cross-section of iron core, N2:Number of turn.
In the present set up, the magnetization curve and Hysteresis curve as function of the magnetic field strength H is plotted.
