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.
edit Units. The units which represent the strengths of the electric and magnetic field are also different. The strength of the magnetic field is represented by either gauss or Tesla. The strength of an electric field is represented by Newton per Coulomb or Volts per Meter.
