To increase the magnetic force exerted by the electromagnet, the student should add more batteries in series at location 3. This increases the voltage applied to the electromagnet, which in turn increases the current flowing through the wire and enhances the magnetic field strength produced by the electromagnet.
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
