Lab manual for the CASSY Hysteresis experiment covering aims, equipment, setup, and measurement procedures.
This manual describes the magnetic hysteresis laboratory experiment conducted with the CASSY sensor system. It outlines the learning objectives, provides background theory, and lists the required equipment such as the Sensor‑CASSY, U‑core, coils, function generator, and power supplies.
Step‑by‑step instructions guide students through building the experimental setup, configuring the function generator, correcting measurement offsets, performing measurements, and analyzing the hysteresis loop. Hints and troubleshooting tips are included to help achieve accurate results.
| Coils turns | 500 turns |
|---|---|
| Function generator model | 512 |
| Power supply voltage | 12 V DC |
| Resistor rating | 10 Ω, 2 W |
Set the function generator to a sawtooth waveform with a frequency around 0.1 Hz and an amplitude of 1–2 V (1 V is recommended).
Open Settings → Ug, select Correct, set the first target value to 0 V, and click Correct Offset.
Both the function generator and the Sensor‑CASSY need to be powered from the 12 V external DC supplies.
Use the peak integration function; the integral value appears in the lower‑left corner of the display.
