  • ID Code: K2-21
  • Purpose: Demonstrate induction of a very high voltage using a small voltage source.
  • Description: The Ruhmkorff coil is a classical transformer that uses a vibrating interrupter mechanism to create high-voltage pulses from a low-voltage direct current. They were widely used in industry and research in the late 19th and early 20th centuries, but are now largely used for educational purposes. Interestingly, automotive spark plugs are a descendant of this technology.

    In this experiment, a 7.5 volt battery is connected to the input of a high-voltage Ruhmkorff induction coil. The induced voltage will produce a 1"-2" spark. Note: Please be careful not to touch the electrodes until after the coil is fully discharged.
