Answer:
First things first, you'll need a ferromagnetic core - something like iron or steel works best. The more turns of wire you have around the core, the stronger your magnet will be. So don't be scared – wrap that wire around as many times as it can handle! And speaking of wire, consider using thicker wire with low resistance to maximize current flow. That means more power flowing through your magnet. Another trick is to increase the voltage of your power source, but be careful not to fry anything in the process! Lastly, if all else fails and you're still not satisfied with your magnet's strength, you can always resort to using a bigger battery or power supply. Just remember to handle electricity with caution and don't go too crazy!
