A student wants to compare the magnetic strengths of three different electromagnets by winding similar kinds of insulated copper wires on three similar iron nails as shown in the image. She brings each of the electromagnets near a pile of paper clips and records the number of paper clips attracted to each electromagnet in a table.
Which conclusion is supported by the data?
Responses
The strength of an electromagnet cannot be predicted based on the number of coils.
The strength of an electromagnet cannot be predicted based on the number of coils.
The strength of an electromagnet increases as the number of coils increases.
The strength of an electromagnet increases as the number of coils increases.
The strength of an electromagnet does not depend on the number of coils.
