Electromagnetic Rail Twirler

Electromagnetic Rail Twirler

This is a classic toy with a little twist.

In the classic version, the rod running through the wheel is a magnet and the rail is simply some ferrous material. This ensures that the wheel always stays on the rail no matter which direction it is facing.

In this version, the rails are not ferrous but are electromagnetic. When the button is pressed, the electromagnetism is activated. When the button is released the magnetic field dissipates and the wheel is no longer attached.

This allows kids to throw the wheel off of the rail and into the air and attempt to catch it. Because the wheel is fairly small and light, it poses little danger to its environment.

This toy is slightly more expensive due to the solenoid electromagnetics contained inside.
