I didn't quite understand the capacitor explanation... I just know the following. In order to obtain a very HIGH VOLTAGE in the secondary, we need a GREAT FLUX CHANGE through the core (implicitly secondary coil), because the greater the flux change the greater the voltage obtained. Therefore, besides collapsing the flux in the primary, we ALSO REVERSE the current direction through it, obtaining a GREATER FLUX DECAY through the primary, and this is exactly what the capacitor does. A capacitor always opposes a build up in voltage by charging itself. The contactor circuit here shortens both the primary coil and the capacitor. Let's assume the rotor starts from Full Register, with N in the left, rotating clockwise. The capacitor opposes the build up of the induced voltage in the primary by charging up, and immediately after the circuit opens (10 degrees after Neutral, EGAP), the capacitor is no longer shortened by the contactor, so it discharges solely through the primary coil. Keep in mind, that any collapsing magnetic field through a coil, give rise to a self induced current through that coil. In our case, the self induced current due to the collapsing magnetic field is opposed by the capacitor current through the primary, thus hurrying up the collapse (according to the Right-Hand Corkscrew Rule) ! In other words, the capacitor only forces a reversed current through the primary, to oppose the selfinduced one, in the end accelerating the collapse of the induced magnetic field. This happens very quickly, right after 10 degrees past Neutral (EGAP). At this point, the CHANGE of the rotor magnetic field in the core is just below peak value, which means the EMFs generated in both the primary and secondary coils are just below maximum. Also, the CHANGES in the rotor magnetic field and the collapsing primary field have the same directions (very important)! As the two magnetic fields have the same direction of change, they will superimpose, thus give rise to a LARGE FLUX CHANGE through the core, implicitly through the secondary coil. This is like a spike in the magnetic flux change through it, leading to a very high EMF at the ends of the secondary, which translates in a spark obtained at the sparkplug. In other words the capacitor and primary coil form a tuned LC circuit. All this starts when the EGAP commences and up to the point when N reaches the yoke (Full Register position), the superimposed flux change being large enough to create the spark. th-cam.com/video/OMLSNwQiiKg/w-d-xo.html
hi, you write on one side the advantage of magneto is you dont need a battery. on the other side you say the disadvantage is you need a battery. why do you need a battery?
I think a battery is needed while starting the engine, the initial "push" for the magnet to start rotating. After that, the crankshaft takes care of this, so a battery is not needed further. This is just what I think, I'm not sure about it though.
Osm sir nice explanation
Very helpful and very easy to understand everything....thank you

Very informative my dude!
Much more better with animation👍
very good it was simple
Nice explanations
Thank you sir .
Keep rocking 👏👏👏👏👏🙌
Very very nice 😍😍
Can u make a vedio on types of Splash lubrication
Yes sir..
Aapka sab video dekhe or like kiye
nice
You are literally reading it!! .... Didn't really got the concept
Dw bro.. i will make anothrr video on the same topic.
Sir magneto ingnition system Motor cycle me kiske through rotate karta hai
Crankshaft ke through
Ya gear box through
How will engine start without power or cranking start without power...4.25
What about the shield type magneto? Armature and magnets does not move.

Sab sahi hai bhai ! But when will you stop reading and start explaining ?

Explanation is very fast .......it consuming more time
Where the magneto ignition system is currently in use??
....🤔🤔
BE B :- 02
Plzz explain deeply like a mechanical engineer
yes sure !!
Broo plzz add some animation videos
To better understanding...
Thank u broooo....

It would be nice if you could be understood and speak in plain English and not rush through what your reading
very poor

no offense but you need to improve your grammar.
Okay bro 👍
