Demonstration DC Motor, 1 Each

The United Scientific® Demonstration DC Motor is a pre-assembled, open-structure motor that resembles the textbook diagram, helping students learn about electromagnetic forces. Magnet polarity can be reversed to change rotation, and a rheostat can be added to show speed varying with current. It runs on a 1.5 V battery, stands vertically or horizontally, and comes with a storage case and activity guide.
