This kit is almost the same as Kit #11 but includes ready to use electromagnet. It cuts assembly time and this simplest motor could be built in less than 20 minutes!
This motor uses strong neodymium magnets secured by safety ring. No messy glue is needed for assembly and no tools required.
It is really fast – over 2500 RPM on just one 1.5 Volts battery. The precision of modifications on this motor kit matches the precision of original parts with tolerances up to +/-0.03 mm (this is 1/10 of human hair thickness!). You need such accuracy to achieve this speed and power.
Despite its simplicity it is a perfect learning tool to make first steps into wonderful world of electricity and magnetism.
It fits into tight classroom schedule – short assembly time leaves the opportunity to discuss physics principles of motor operation and other related materials with your students.
It could be also used for birthday parties and other activities and makes a great gift!
