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
H=(N1/L).I1
where L: Effective length of iron core, N1: Number of turns in primary, I is the current in primary coil of transformer.
The corresponding magnetic induction B is obtained through integration of the voltage V2 induced in secondary coil as:
B=(1/N2.A). V2.dt
where A: Cross-section of iron core, N2: Number of turns in secondary. In the present setup, the magnetization curve and Hysteresis curve as function of the magnetic field strength H is plotted.
