Joule Gun

This highly original apparatus offers an exciting application of topics such as energy storage, capacitor charging, mechanical energy, efficiency and electromagnetism. The control box provides five high value capacitors which can be switched into the charge circuit as required. When the FIRE button is pressed the energy stored is released as a pulse into a low resistance coil to fire a small steel projectile. Variables include, voltage, time, capacity, distance, kinetic and potential energy. Applicable to many topics at GCSE and Post-16.
Ships with a 15 page experiment booklet.
