Use the diagram below to answer the following question: Which procedure step could the student follow to make the magnetic force exerted by the electromagnet greater? (1 point) Responses increase the length of wire at location 1 increase the length of wire at location 1 open the switch at location 2 open the switch at location 2 add more batteries in series at location 3 add more batteries in series at location 3 reduce the number of wire turns at location 4
The procedure step the student could follow to make the magnetic force exerted by the electromagnet greater is to add more batteries in series at location 3.
