Lina did an experiment with an electromagnet. Above is the data she collected.What can you infer from the data in the table ?

30 coils will hold 50 paperclips

Using more coils increases the strength of the electromagnet

15 coils hold twice as many paperclips as 10 coils

The more coils, the fewer paperclips the electromagnet will hold
