— In 1820, HANS CHRISTIAN OERSTED discovered that an electric current
had an effect on the needle of a magnetic compass.
— We reenact the Oersted experiment, which opened the entire field of
— See with your own eyes that magnetic fields can PENETRATE SOLID WALLS!
— We show how to generate magnetic fields with the help of AIR
SOLENOIDS and of iron-core ELECTROMAGNETS.
— The main event will be the demonstration of a COIL GUN which shoots
pieces of steel coat hangers. The energy powering the gun is stored in
a 5000 microfarad electrolytic capacitor.
