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 electric field strength is inversely related to the square of the distance. So by whatever factor d changes by, the E value is altered in the inverse direction by the square of that factor. The specifics are as follows: b) d decreases by a factor of 2; multiply the original E by 4.
