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:

B=(1/N2.A). V.dt

where A: Cross-section of iron core, N2: Number of turn.
In the present setup, the magnetization curve and Hysteresis curve as function of the magnetic field strength H is plotted.
