1. The coils of wire carrying a current are behaving like a magnet. This can be determined by observing that the compass needle aligns itself with the magnetic field created by the current-carrying wire, indicating the presence of a magnetic field.
2. Changing the voltage of the battery from 10V to 2V will affect the strength of the magnetic field. As the voltage decreases, the current flowing through the coils of wire will also decrease, resulting in a weaker magnetic field.
II. Electromagnet Questions:
1. For this investigation, is it the Battery or the Coils of Wire carrying a current that are behaving like a magnet? (Hint: Use the magnetic field and compass to help you decide.)
