Electric motors are one of the most fascinating inventions of the twentieth century. They leverage the power of induction to create motion from electricity.
Electromagnetism is one of the most important forces that we know of in physics. You may be familiar with magnets and electricity, but did you know that one can generate the other? You can use magnets to induce an electric field by causing electrons to move around, and when electricity flows, a magnetic field is created around it! This principle is used to create electric motors.
You will create three little robots with motors, Big Foot Bot, Bug Bot and Crawl Bot!
