About This Product
An induction coil uses a make and break contact to interrupt a low-voltage D.C. current in the primary, which induces a high voltage in the secondary and produces a spark. It is used in school physics to show electromagnetic induction and the effect of the number of turns. Mutual and self inductance coils are used to study how a changing current in one coil induces a voltage in a second coil or in itself.
Frequently Asked Questions
Q1. What supply does the Induction Coil work on?
The spark coil works on 6-12 volt D.C. A separate version works on 220 volt A.C. mains and gives a 25 mm spark.
Q2. Which spark lengths are listed?
The D.C. version is listed with spark lengths of 5, 10, 15, 20, 25, 50, 75, 100 and 150 mm.
Q3. Which other coils are listed under Induction Coil?
Mutual and self inductance coils with primaries of 500 or 3000 turns, a self induction coil of 3000 turns with an adjustable soft iron core, and a model for use with a Kohlrausch conductivity bridge.
