What the Expert Says:

The dependent variable is the wire looping through the 2 magnets. The independent variables are numerous, including the table, the pencil, the two magnets and their magnetic field, the battery, the type of wire, the room temperature, etc.

What the Expert Says:

The dependent (responding) variable is the wire looping through the 2 magnets. The independent (manipulative) variable is the current produced by touching the wire to complete the circuit with the battery. The constants are numerous, including the table, the pencil, the two magnets and their magnetic field, the brand of battery, the type of wire, the room temperature, etc.
