Parker wound a wire around a large iron nail. He then created an electromagnet by connecting the ends of the wire to different batteries. The table shows the current he measured for each electromagnet.
A 2-column table with 4 rows. The first column labeled Electromagnet has entries W, X, Y, Z. The second column labeled Current (Amperes) has entries 2, 5, 8, 3.
Which conclusion is best supported by the data?
Electromagnet W is the strongest.
Electromagnet X is weaker than electromagnet Z.
Electromagnet Y is the strongest.
Electromagnet Y is weaker than electromagnet X.
