Investigate the principles of Lorentz forces by constructing an apparatus to levitate conductive objects using electromagnetic fields. This project involves detailed analysis of magnetic and electric field interactions.
If a strong enough magnetic field interacts with a conductive material, it will induce a current that generates a Lorentz force to counteract gravity, causing levitation.
