Our PBL Project is based is called Homopolar Motor. This project is based on working two main thing like magnesium and electricity. Our project demonstrate the Lorentz Force.
The Homopolar motor creates a rational movement because of the Lorentz Force. The electoral current is flowing from the positive terminal of the battery to the negative and into the magnet. The current then flows from the center of the magnet into the edge where the wire connects, it travels up the wire back to the positive terminal of the battery and finally the circuit is complete. If the battery has less charge the conductor(wire) will not move due to the battery not being charged. If there is no current flowing through the wire then it wont create a magnetic field. That means the battery is not fully charged. The magnetic field is space near a magnet, electric current, or moving charge particle in which a magnet force acts on any other magnet, electric magnet, or moving charged particle. The more loops or coils the faster the wire will go because there are more current through the wire. Which will create magnetic field. The homopolar crates a rotational movement due to the Lorentz Force; the electric current is flowing from the positive terminal battery to the negative into the magnet. If the conductor (wire) does not move around the battery it means that the battery has no charge inside the battery. If there is no charge inside the battery then that means the conductor (wire) will not move. Michael Faraday first demonstrated the homopolar motor in 1821 and there was no confirmation of what he used. It could either be a single AA or C battery, a neodymium disc magnet. or a piece of wired copper.
The Keywords and units are Lorentz Force, magnetic field, and electromagnetism.
