An induction coil consists of two coils of insulated copper wire wound around a common iron core. One coil, called the primary winding, is made from relatively few (tens or hundreds) turns of coarse wire. The other coil, the secondary winding, typically consists of many (thousands) turns of fine wire. An electric current is passed through the primary, creating a magnetic field. Because of the common core, most of the primary's magnetic field couples with the secondary winding. The primary behaves as an inductor, storing energy in the associated magnetic field. When the primary current is suddenly interrupted, the magnetic field rapidly collapses. This causes a high voltage pulse to be developed across the secondary terminals through electromagnetic induction. Because of the large number of turns in the secondary coil, the secondary voltage pulse is typically many thousands of volts. This voltage is often sufficient to cause an electric spark, to jump across an air gap separating the secondary's output terminals. For this reason, induction coils were called spark coils. The size of induction coils was usually specified by the length of spark it could produce; an '8 inch' (20 cm) induction coil was one that could produce an 8 inch arc.

In an induction coil the distance between the plates is often used to measure the voltage of the spark since the air breaks down at 30 000 volts per centimetreballarat college of advanced education, scientific instrument, induction coil, scientific instruments, electricity

This label comes from the Warrnambool pharmacy of H.W.Shilton. It appears to be a cardboard stopper inserted into the top of a bottle. Harry Shilton’s business was at 119 Liebig Street. He commenced in 1938 when he purchased the business from Ralph Barnes. In 1953 Alan Anderson went into partnership with Harry Shilton. The latter retired in 1960 and in 1967 John Lindsay became the proprietor of the pharmacy business. This label is of minor interest as a memento of a 20th century Warrnambool chemist and as an example of a cardboard bottle top insert. This is a round piece of light card with a blue border and blue printing.H.W.Shilton Pharmacist Warrnambool No………h.w. shilton, warrnambool chemist, history of warrnambool
