The Solenoid Invention Kit

A solenoid is a coil of conductive wire that generates a magnetic field when electric current flows through it. This discovery made many other inventions possible, including the telegraph, the telephone, electric motors, radio, television, computers, and smart phones. Because the solenoid contains the foundational scientific principles that led to so many other inventions, we selected it as the first invention in the FabNet Invention Kit series. Students will discover, explore, and interact with these principles while following in the footsteps of these early inventors.
