Coil Windings
Each time the magnetic field washes through
wires
An electrical current is produced
Called an EMF Electro Motive Force
IGNITION SYSTEM Faraday Law
4
Magneto Operation
EMF produced in the coil windings
The magnetic field passes through soft iron core

5
No EMF produced in the coil windings
No magnetic field in soft iron core

6
EMF produced in the coil windings again
The magnetic field passes through soft iron core
again
