An electromagnet's strength is influenced by a number of factors, including the coil's current, number of turns, and core cross-section. An electromagnet's strength can also be improved by utilizing a core with a bigger cross-section. However, reversing the battery's polarity will just flip the electromagnet's poles. It won't have any effect on how powerful the electromagnet is.
