Use the table of information about four electromagnets to answer the question

Which electromagnet will produce the strongest, magnetic force

To determine which electromagnet will produce the strongest magnetic force, we need to look at the number of turns of wire in each electromagnet. Generally, the more turns of wire, the stronger the magnetic force.

From the table, we see that Electromagnet D has the most number of turns of wire, with 500 turns. Therefore, Electromagnet D will produce the strongest magnetic force.
