DC Motor - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

A metal disk added between the two poles of a permanent magnet, when a current passes through the disk in the radial direction, the magnetic field exerts a force (Ampere force) on the current, causing the disk to rotate. By exhibiting, the audience can understand Ampere's force and reveal the working principle of DC motors. Participants hold metal rods and insert them from two different positions. The distance from the magnetic field varies, resulting in different rotational speeds and Ampere forces on the copper disk. The closer the distance from the magnetic field, the faster the rotation speed of the copper disk, and the farther it is from the magnetic field, the slower the speed of the copper disk.
