How does a magneto ignition coil work?
How Does Magneto Ignition Work? The magneto is a self-contained generator of high voltage that provides ignition to an engine through spark plugs. The moment the contact points open, a rapid magnetic flow generates a high voltage in the secondary coil, which ignites the spark plug, thus firing the engine.
How does a magneto stator work?
The principle behind a magneto is the exact opposite of an electromagnet. Whereas an electromagnet uses electricity passing through a coil to produce a magnet, a magneto uses a magnetic field in the vicinity of a coil, called the armature, to produce an electric current.
How does a magneto generate electricity?
Generating Electricity in the Magneto There is a permanent magnet on the spinning flywheel. When it spins past the primary coil of wire, a current is generated which passes down the wire under pressure towards the secondary coil. The energy of motion is changed to electrical energy.
How does a magneto ignition system work in a scooter?
Magneto ignition system is used in some scooters. Both the systems work on the principle of mutual electromagnetic induction. Electronic ignition systems use solid-state devices such as transistors and capacitors. In this case magneto will produce and supply the required current to the primary winding.
Where does the current go in a magneto coil?
If a component in the system is able to allow that induced current to find a path of least resistance, a ground, the current will go there instead of making its way to the electrode of the spark plug to jump the gap. Most common components to check in the ignition, refer to your service manual for more detail and proper procedures.
How does a magneto work in a generator?
When you apply current to the electromagnet’s coil (e.g. with a battery), the coil creates a magnetic field in the armature. In a generator, you reverse the process. You move a magnet past the armature to create electric current in the coil. A magneto consists of five parts: An armature.
How does a spark plug in a magneto work?
This switch breaks the flow of current through the primary coil and causes a voltage spike (of perhaps 200 volts). The secondary coil, having 100 times more turns than the primary coil, amplifies this voltage to approximately 20,000 volts, and this voltage feeds to the spark plug.

How many Poles are in a magneto ignition coil?
The magnets substituting the battery and ignition coil, has a four-pole magnet, two pole shoes, the primary and secondary coils. When the magnet rotates, the direction of the magnetic flux through the soft iron core of the coil reverses direction.
How does a magnet spin in a coil?
A magnet—hence magneto —spins in close proximity to a coil of wire. As the magnet spins (or the magnet rotor is turned), it generates a strong magnetic force that is “held back” by a primary coil.
How do you test a magneto coil on a bike?
Learn how to properly test your magneto, stator or pickup coils. This works for breaker point and CDI type ignition systems. The main tools you will need to do these tests are 1) The Service Manual for your particular bike 2) an inexpensive multi-meter to measure ohms of resistance. How does one go about diagnosing a “no spark” situation?
