Description

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.

Used as a "test" for lessons in electricity and magnetism. Teams of three fifth graders assemble these motors in about 20 minutes and then compete to see who's motor runs the fastest. Good fun and competition. Building success rate - about 80% running in 20 minutes. They have the three key parts of an electromagnetic motor: stationary field, rotating field and commutator

I usually have my students make their own motors, but this is the second year I have used these and I and my students really like them and they are inexpensive.

This is a great demonstation piece. It is easy to assemble and makes the workings of a motor easy for anyone to understand.

Very nice demo; tricky to build

This kit is an excellent demonstration of basic motor principles. It exactly mimics the function of a permanent magnet DC motor and helps students understand the production of magnetic fields by an electric current as well as the production of torque by orthogonal fields. However, a successful, operating build is difficult and requires care to align the wire ends with the center of the wire loop. My seven-year-old grandson enjoyed this but I had to do a fair amount of 'tweaking' to get his version working. The contact area is prone to oxidation and needs frequent cleaning. This is a bit easier to build than a similar motor I constructed 53 years ago at age 10 from 16 penny nails and a spool of magnet wire. THAT taught me the value of persistence - this one can, too, but it can also generate a lot of frustration w/o good supervision.

Super simple to put together. Worked on the first try. I added a glue dot to keep the magnet from falling out when I turn it over.

Love the demonstration capabilities of this product. I did find that it was not "simple" to put together on the first try.

My students love making their own simple motor, but our school doesn't have enough money to buy one of these for each student, so I have them make their own using the instructions at http://www.youtube.com/watch?v=it_Z7NdKgmY. When you build your own, the students can experiment with different types of magnets. Also, the most difficult part of the simple motor is making the wire coil even on both sides so it will spin. Unfortunately, with this purchase, you still have to wind your own coil.

I was very disappointed in this product. Three teachers could not get this motor to work.

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

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.

Suggested Science Idea(s)

DCI/HS-PS.A

Students can use the World's Simplest Motor in a number of investigations when exploring electrical energy and magnetic fields.
