5x5mm Rod Magnets

A reed switch motor is a simple, electric DC motor you can build for a science fair project. Use it to demonstrate an experimental procedure of how a reed switch can work in a magnetic circuit. Why spend $30 or more on an off-the-shelf simple motor kit when you can DIY for a fraction of that, especially if you are a teacher on a budget?

There are many designs available but two permanent magnets such as our 5x5mm neodymium discs, some reed switches & jumper wires are readily available. Other key parts can be found in electrical supply or hardware stores. Alternatively, you can repurpose some of the 19 gauge copper wire & battery holder from our Electric circuits kit.
