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.
An electromagnet can be regarded as a temporary magnet that functions with a flow of electricity, and its polarity can be easily altered by varying the direction of current. On the other hand, the magnetic strength of electromagnets can be changed by varying the amount of current flowing through them.
