An iron core will produce the strongest magnet. By increasing the size of the core you also increase the strength of the electromagnet. Compare the diagrams. Note: Look at the amount of coils, the size and number of the power source.
The Effect of the Number of Coils on an Electromagnet On Its Strength. Aim: - To establish whether a variation in the number of coils will. affect an electromagnet's strength. Scientific Knowledge: -. The concept of electromagnets is fairly simple. An iron nail wrapped in a series of coils of insulated wire and then.
