With the DC Motor Demonstration, study electromagnetic forces. The open structure resembles textbook diagrams and allows one to see how the motor works.
Study electromagnetic forces with this pre-assembled DC motor. The open structure resembles textbook diagrams and allows students to see how the motor works. Reverse the polarity of the magnets to change the direction of rotation. Use the motor with a rheostat to observe how speed changes are relative to current changes. A power source of at least 1.5 V is required and available separately. 5½" x 4½" x 2½".
