INDUCTION COIL (PEES-1016) size:50mm Spark the cube helps visualize refractionUseful for the demonstration of characteristics associated with high voltage phenomena such as with Geissler tubes, spectrum analysis tubes etc. This traditional induction coil is capable of producing a spark length of up to 25mm with an input of 6 to 8V DC and is therefore ideal for use with vacuum tubes, eudiometers, etc. A fully adjustable trembler system is incorporated and spark suppression capacitors are housed in the base.
