Description
High quality, trembler type spark coil. comprising primary of few turns of heavy wire wound on iron core, mounted horizontally, which is fed by DC current pulses. Secondary coil of very large number of turns of very thin gauge wire completely encompasses the primary and is impregted with wax. The electromagnetic induction due to current passing through the primary makes the armature oscillate resulting in frequent switching ON/OFF of the current through primary. This produces extremely high rate of change of magnetic field in this Rhumkorff’s coil, giving rise to a potential of several thousand volts in secondary, which is observable in the form of repetitive spark up to 25mm long across adjustable needle. Provided with a safety spark gap beneath needle socket termils to protect interl damage to the coil against very high voltages. Output from the termil can also be used to operate high voltage devices such as spectrum tubes etc. operates on 6-9V DC.
