WebFeb 16, 2024 · Collapsing the field induces electric currents in both windings. For ignition coils (and many types of electrical transformer), the secondary winding is made with more windings than the primary winding. When the magnetic field collapses, it will therefore induce a higher voltage into the secondary winding than into the primary winding (Figure 6).

How Does an Ignition Coil Work? It’s a Windings Road! - MotorTrend

WebInstantaneously, when the points open (separate) current flow stops through the primary windings of the ignition coil. This causes the magnetic field to collapse around the coil. The condenser absorbs the energy and prevents arcing between the points each time they open. This condenser also aids in the rapid collapse of the magnetic field. WebA primary winding is the winding of a transformer that is connected to and receives energy from an external source of electrons . A transformer is an electromagnetic device that has …
