6. **Testing and Insulation:**
- Fill the system with water (e.g., 5 liters at an initial temperature of 13°C).
- Spin up the magnet disc using a pillar drill or a motor.
- Monitor the temperature change. Note that without insulation, heat will radiate away quickly.
- To improve efficiency, wrap the system in insulation to retain as much heat as possible.
