ABSTRACT:
A simple motor device for use as a learning tool includes a battery, a permanent magnet, an electrically conductive wire coil, a housing having an open bottom and parallel sidewalls to accommodate the battery, slotted grooves vertically traversing the sidewalls on an interior portion of the housing and forming openings at the top of the housing, E-shaped portions formed on both ends of the interior portion of the housing, and two specially adapted metallic supports that are positioned within their respective slotted grooves and extend through the openings on the top of the housing. One end of each metallic support contacts one end of the battery while the other end has an open yoke to electrically contact and support one end of the electrically conductive wire coil. A sub-housing portion of the housing is designed to accommodate the permanent magnet. The electrically conductive wire coil can rotate via the battery current running through it and the magnetic field produced from the permanent magnet. The motor of the present invention is securely held together once assembled due to specially adapted components.
