    Induction Coil Ruhmkorff

    Induction Coil Ruhmkorff

    SKU: 0914-0803 Category:

    Details:

    • Induction Coil/ Spark Coil instrument is an electric transformer, used to produce pulses from high voltage to low voltage direct current supplier.
    • This coil is used in x-ray machines, ignition coil for internal combustion engines and also used in physic labs to demonstrate induction.
    • This coil consists of central cylindrical core of soft iron, which contains two insulated coils: an Inner/ Primary Coil, Secondary Coil.
    • The Primary Coil having relatively few turns of copper wire, and a surrounding secondary coil, having a large number of turns of thinner copper wire.

    Induction Coil Spark 5mm

    Induction Coil Spark 5mm

    SKU: 0914-0804 Category:

    Details:

    • Useful for the demonstration of characteristics associated with high voltage phenomena such as with Geissler tubes, spectrum analysis tubes.
    • This traditional induction coil is capable of producing a spark length of up to 30mm with an input of 6-8V 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 Rhumkorff commentator allows primary current to be both reversed and switched ON/OFF with make-and-break point.
    • A pair of pointed electrodes is supplied with the instrument, the pointed electrodes having an insulating handle for adjustment of the spark gap. Low voltage input is provided via a pair of baseboard mounted color coded 4mm sockets.
