IGNITION SYSTEM – Faraday’s Law S S S S N N N N S S S S N N N N Coil Windings Volt Meter Each time the magnetic field ‘washes’ through a coil of wires, an electrical current is produced.This is called an EMF – Electro Motive Force Or the opposite is true for this principle. If you supply electricity through a coil of wires, a magnetic field is created.

Magneto Operation EMF produced in the coil windings The magnetic field passes through soft iron core IGNITION SYSTEM IGNITION SYSTEM
No EMF produced in the coil windings No magnetic field in soft iron core IGNITION SYSTEM
