This easily assembled motor is able to run for more than five hours on a simple D-Cell (flashlight battery). Recommended for ages eight and up. Requires D-Cell battery, not included.
Replacement wires are also available. You can buy a class set of our World's Simplest Motors and have students wind their own armatures year after year. The wire is the same used in the original kit.
Need replacement magnets? Our M-187 neodymium ring magnets
make great replacements and are even stronger than the originals.

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s) DCI/HS-PS.A
| Elementary || || Middle School || || High School |
| K-2-ETS1-1 |
Students can use the World's Simplest Motor to ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool. 3-PS2-3
Students can use the World's Simplest Motor to ask questions to determine cause and effects relationships of electric or magnetic interactions between two objects not in contact with each other. 4-PS3-2
Students can use the World's Simplest Motor to make observation to provide evidence that energy can be transferred from place to place via electric currents.
| || MS-PS2-5 |
Students can use the World's Simplest Motor to conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact. MS-PS3-5
Students can use the World's Simplest Motor to construct, use, and present arguments to support the claim that when the motion energy of an object changes, energy is transferred to or from the object. MS-ETS1-2
Students can use the World's Simplest Motor to evaluate complete design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
| || HS-PS2-5 |
Students can use the World's Simplest Motor to plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current. HS-PS3-2
Students can use the World's Simplest Motor to develop and use models to illustrate that energy at the macroscopic scale can be accounted for as either motions of particles or energy stored in fields.
Students can use the World's Simplest Motor in a number of investigations when exploring electrical energy and magnetic fields.
