How to draw a detailed diagram to explain in detail a scrap heap magnet works?

To draw a detailed diagram of how a scrap heap magnet works, start by illustrating the magnet itself, typically an electromagnet, with labeled components such as the power source, coils, and core. Include arrows to indicate the direction of the magnetic field and highlight how the magnetic field attracts ferrous metals. Add labels for the scrap heap and show the magnet in action, demonstrating its movement over the metal debris. Finally, include annotations explaining the process of turning the magnet on and off to control its attraction.
