Noun
coil forming the part of an electrical circuit such that changing current in it induces a current in a neighboring circuit

A capacitor is placed across the points which absorbs the energy stored in the leakage inductance of the primary coil, and slows the rise time of the primary winding voltage to allow the points to open fully. Source: Internet
As the field collapses rapidly there is a large voltage induced (as described by Faraday's Law ) across the primary coil. Source: Internet
As the points begin to open, point spacing is initially such that the voltage across the primary coil would arc across the points. Source: Internet
This causes the electromagnetic field in the primary coil to collapse rapidly. Source: Internet
