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.
Applications of electromagnets. The ability of electromagnets [electromagnets: Magnets made by wrapping a coil of wire around an iron bar and passing an electric current through the coil.] to attract magnetic materials (iron, steel, nickel and cobalt) makes them useful in many ways.pplications of electromagnets.
