RHUMKORFF COIL (SPARK COIL) 25mm SPARK 12V.DC

  • EM3450-001

The IEC Rhumkorff's Coil (or Spark Coil) has been used in Australian schools for many years. The vibrating points are tungsten and a high quality capacitor is used to reduce arcing. A fuse is fitted to protect the primary winding. The secondary winding, containing thousands of turns, can be slid from the primary to reduce the coupling.
The unit runs from about 6 to 9V.DC. and a spark length of about 25-30mm long is normal. It is complete with removable and adjustable needle points with insulated handles.
Should be used only with supervision.


CAUTION: Be careful touching this instrument
when it is running because very high voltages
are generated at the adjustable needle point
spark gap.
Spark gaps can produce X ray and UV
radiation. Although risk is very low, do not
come closer than necessary to the spark
discharge and avoid being closer than about 2
metres for prolonged periods.
