To increase the strength of the electromagnet, the student can add batteries to increase the voltage and decrease the space between the coils of the wire. Increasing the voltage will generate a stronger magnetic field, while decreasing the space between the coils will enhance the concentration of the magnetic field.

To increase the strength of the electromagnet, the student can follow these steps:

1. Add batteries to increase the voltage: The strength of an electromagnet is directly related to the voltage applied. By adding more batteries in series, the voltage across the copper wire will increase, resulting in a stronger magnetic field.

2. Increase the space between the coils of wire: The magnetic field produced by an electromagnet is also affected by the number of turns/coils of wire. By increasing the space between the coils, the magnetic field lines can spread out more, resulting in a stronger magnet.

So the correct response is: Add batteries to increase the voltage, and increase the space between the coils of wire.
