- connected in series to secondary windings by two electrodes
- bypasses secondary windings if path is interrupted
- helps protect the secondary windings in the coil to provide an alternate path for current if there is an open in the secondary circuit

What is mmf?
Full-form Of MMF: MAGNETO MOTIVE FORCEDefinition Of MMF ( Magneto motive Force ): Just as electromotive force ( emf ) is necessary to pass current in electric circuit, magneto motive force ( mmf ) is necessary to establish flux in the magnetic circuit. Magneto motive force is the multiplication of current flowing through the coil and the number of turns of the coil.Unit of magneto motive force ( mmf ) is ampere turn.Thus, it should be understood that the magneto motive force can be increased by increasing the number of turns in the coil or by increasing the current flowing through the coil or by increasing both.CommentThe unit of measurement of magnetomotive force is actually the ampere, although it is frequently spoken as 'ampere turn' to prevent its confusion with electric current.
What is magneto optic current transformer?
moct is device measure the current by means of faraday's effect..
Magnetic-potential drop occurs across the air gap?
There is a magnetic-potential drop across an air gap. If you represent a magnetic core with a winding current i as a magnetic circuit. The magneto-motive force will be your voltage source, where the mmf (magneto-motive force) = Ni; (number of turns on the core and current product) == ∫Hdl=mmf=N*i. The elements that would be in the circuit would be in series and it would be represented as two "resistors" or better known in magnetics as the reluctance of the material which has a parallel equivalence to the resistor's characteristics.Reluctance=Rmk=length of material divided by the product of the Area and permeability of the material µ.Rmk=lk / (µk*Ak); where k is the number of of "legs" of the core or different mediums you approach.To answer the air gap problem, the air gap would have a Reluctance where µ = µ0, permeability of free space and the Area of the Magnetic flux would be the same size of the area of the core. Finally the length would be the size of the airgap=δ.Now since you have the reluctance of the airgap rmδ= δ /(µ0*Area of core). The Magnetic Drop is now = Umk where k is δ = Umδ = mmf / Rmδ = µ0*Area*N*i/δ
What role does switch play in an electric circuit?
a switch is used to isolate the a flow of current through a circuit , by breaking its connection, there is often a switch at the beginning of a circuit which would isolate the supply - voltage , from the load or " circuit " , in terms of higher - rated voltage circuits ( mains power) ; the switch performs a safety function where it provides a quick , safe and effective means of swathing off the circuit , providing a safety function - purpose , allowing the user to quickly remove power in the event of an emergency , for the switch to carry out its duty, it needs to have an air gap across its contacts contained within , rated so that at the designed/ rated voltage it maintains safety isolation / not allowing an electric arc / spark to jump across the gap .
What is the circuit diagram of magnetostriction oscillator?
magneto striction oscillator is used to produce ultrasonic waves by using the the principle of inverse piezo electric effect
What is the gap setting for a ryobi magneto?

1965 harley Davidson sportster spark plug gap with fairbanks mosre magneto?
I believe its .020 with a magneto.
Briggs and stratton 6.75 magneto gap?
Most of the Briggs engines can be gapped simply with a business card between the flywheel and the magneto.
What is Yamaha 2hp outboard points gap?
The magneto point gap on a 2hp Yamaha outboard is 0.35mm, or 0.014".
Magneto gap for 8 hp Briggs and stratton engine?
.010mmType your answer here...
The magneto air gap is a precision measurement thats taken between the?
The magneto air gap is a precision measurement that's taken between the edge of the flywheel and the ignition coil armature. The flywheel and the crankshaft are held together in alignment by the flywheel key.
Troubleshoot No firing from armature magneto and spark plug?
air gap improperly set between fly wheel and magneto, bad coil, spark plug harness. Would not hurt to check the spark plug gap and ensure the connector end is tight
What spark plugs are used in a 350 with a magneto?
Use the same spark plugs as you would with a distributor, but reset the gap to .020".
Why do some aircraft have dual magnetos?
Basically the second Magneto is provided as a fail safe. There are a lot of redundancies in aviation, especially when it comes to maintenance and safety. The second magneto on a single engine plane is there to contine to provide a spark to the engine in case of a failure of the first magneto.
What is Ignition Coil gap setting toro mower?
For most small 4 cycle cylinder engines using a magneto and a coil to provide electricity to feed the spark the gap is .006 to .010.
Magneto gap for Briggs and Stratton 15 hp engine?
Most people use a standard business card between the magnetto and flywheel.
Does a small engine flywheel need to be timed?
Yes, on the crankshaft there should be a "slot" called a keyway, and a matching slot on the flywheel, mate a key in the slot of the flywheel and crankshaft, and then your flywheel should be timed, also on a magneto ignition system, makesure the magneto has the proper gap, called "armature air gap" usualy if you put a buossness card in there is a good starting point
