Easy to build, the World’s Simplest Motor kit allows you to build a simple motor to show how it can change electrical energy into motion.  Just requiring 1 D battery (not included), the instructions guide the user through the entire building process, and offers good scientific information on how this works.  Good option for a basic science project or classroom science demonstration.


  • Kit allows you to build a very basic motor to demonstrate how electrical energy is converted to create motion
  • Requires 1 D battery (not included)
  • Comes complete with detailed instructions and suggestions for further experiments
  • Good for a science fair project and classroom demonstrations

5 star rating  Senior engineer retired, high school science teacher
Jon W Syferd from NM, Artesia, USA
30 years teaching experience using Worlds Simplest Motor. Demonstrates transformation of chemically stored energy into induced momentary electromagnetic field interaction with permanent magnetic field to produce motion. Voltage and amperage readings easily taken while the motor is running. For all ages.

4 star rating   Wm Breiland from USA, WA
This is a very clever toy. It has all the parts that comprise a real electric motor and illustrate the principles in a very direct way. However, I can see someone who does not understand the critical parts of the construction not taking enough care. As a result, it will not work. A clear explanation of how the constant and intermittent magnetic fields cause the rotation would be helpful and help the builder to be extra careful in stripping the insulation off only one side of the wire. The instructions do tell you to do this, but not why.

4 star rating  A good instructive electro-magnetism project
Michael from Sandia Park, NM
These simple motors can be built by students with about 30 to 40 minutes effort. They learn about magnetism, electricity and mechanics in one project. About half the student teams of two or three get their motors running and the others are motivated by this success to complete the project. Only a few coils end up hopelessly scrambled so have some spare wire on hand. You also need an exacto knife and/or sandpaper to complete this project. Different levels of students require more or less step-by-step instruction. Instructions included are quite good.
