• ID Code: J7-21
• Purpose: Demonstrate the hysteresis loop for an iron transformer core
• Description: This demonstration shows the standard hysteresis curve with the magnetic induction B plotted on the vertical axis and the applied field H plotted on the horizontal axis. The value of H is obtained by using the voltage across a 1 ohm resistor in series with the 250 turn primary coil of the transformer. The value of B in the core of the transformer is obtained as the voltage across a capacitor in series with a resistor and the 500 turn secondary coil of the transformer. A variac adjusts the primary voltage so that the interesting parts of the hysteresis loop can be seen.
