Principal -
Each time the magnetic field ‘washes’ through wires
Volt Meter
An electrical current is produced
Called an EMF – Electro Motive Force
Coil Coil WindingsWindings
IGNITION SYSTEMMagneto Operation
The magnetic field passes through soft iron core
EMF produced in the coil windings
IGNITION SYSTEM
No magnetic field in soft iron core
No EMF produced in the coil windings
IGNITION SYSTEM
The magnetic field passes through soft iron core again
EMF produced in the coil windings again
