My Homopolar Motor project

Procedure:

A magnet is used to provide external magnetic field in which the conductor will turn, and the battery will cause a current to follow along the conducting wire (It is not necessary for the magnet to be in contact with the rest of the motor). Attach the magnet to the battery and allow the conducting wire to rotate freely while closing the electric circuit by touching both the top and bottom of the battery and the magnet to the bottom of the battery (if operated for to long it may over heat).

Scientific Principles:

• Lorentz force: as it moves through a magnetic field, the conductor is pushed through a magnetic field by opposing forces. The right hand rule is apart of Lorentz force. The right hand rule is used to find the direction of the magnetic field is moving. That the magnetic force is all was perpendicular to both the Velocity and of the magnetic field.

• Torque: applying a twisting force to an object

• Magnetic field: A region where a magnetic force can be detected the magnitude of a magnetic force:

magnetic field= magnetic force on a charged particle/(magnitude of charge)(speed of charge)

• Magnetic field of a current-carrying wire: when a wire is carrying a strong current it causes a strong magnetic force to be created around the wire.

Safety Regulations:

• Use caution when working with sharp objects

• Use caution when working with strong magnets. Keep magnets away from objects that may be damaged by them' and do not allow the magnets to snap together forcefully enough to shatter

• Open circuits before they become too hot. Do not continue operating circuits if they are hot.
