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.
Magnet A has twice the magnetic field strength of Magnet B and at a certain distance pulls on magnet B with a force of 100 N. The amount of force that magnet A exerts on magnet B is. exactly 100 N. Compared to the huge force that attracts an iron tack to a strong magnet, the force that the tack exerts on the magnet is.
