You can make your own electric motor by following the instructions at the website. This electric motor works on different mechanics to convert electrical energy into mechanical energy. This electric motor works through a pulsated DC circuit. When the section of uninsulated wire is in contact with the paper clips, current will pass through the coil creating a magnetic field; the field will either be attracted to or repelled by the magnet under the coil. When the insulated wire on it is in contact with the clips, no current will be in the coil essentially shutting off the magnetic field and allowing the coil to continue spinning using the momentum it gained. |
