To learn about electricity and magnetism and how the two fields are related, complete over 60 experiments with circuits and magnetic contractions. Kids ages eight and up can safely and easily experiment with electric current and magnetic fields using the colorful snap-on blocks and other components included in this hands-on kit. Perform tests to see which materials are magnetic. Learn about the force of magnetism and magnetic poles. Finally, put everything you've learned to good use by building a speaker, an electromagnetic relay switch, and a Morse code telegraph key. The components are specially designed to make learning fun and accessible to every child.
