Discover the power of electromagnetism through this fun experiment! Kids and teens interested in STEAM will love creating their own electromagnetic train while learning about the relationship between electricity and magnetism.
When the battery is placed inside the coil and the magnets on either side of the battery are touching the copper coil, a closed circuit is created with electricity flowing to the positive end of the battery through the magnets to the copper wire and back to the negative end of the battery. The copper wire acts as a conductor for the circuit. The electricity flowing through the copper wire creates a magnetic field. The magnetic field is strongest in the center of the battery at first, but then it spreads out and becomes weaker at the end, creating a non-uniform magnetic field. This causes the magnets in front to feel a stronger push in one direction while the magnets in the back feel pulled, causing the battery to move through the coil.
