Warren,
Yes clearly known as only the wise and advanced group! lol
While in grade 7 the wood shop teacher was showing us how to use the wood lathe.
He turned it on and reached to knock off some loose debris.
The wind from the turning lathe caught his tie , pulled it until the tie ripped.
His tie was very tight. He made some pretty colors until he could cut it off.
If we laughed we were to be sent home!!! lol
Warren , Bridgewater brings me back to my childhood in memories.
I am from an area around the bottom and across the Bay. Just up the road a step.
Alma is a sea going fishing village. Up the road my father ran a make shift scrap/wrecking yard , about 150 -200 cars/trucks
cycling kind of thing. When I was about 7-10 years of age he would have me strip some thing out for the carburetor ,starter,gen,alternator
and hang it with bailer twine . Then say that's for Norms Tornado up the road on blocks ! lol
Bart

Warren, their main HQ is in Wisconsin but they may have had a plant in Canada. Peterborough, Ontario<https://en.wikipedia.org/wiki/Peterborough,_Ontario> - Johnson/Evinrude Outboards (Closed in 1990) Made Ryan lawnmowers. https://en.wikipedia.org/wiki/Outboard_Marine_Corporation Oh, Warren, Bert Pool sent you this.
Tool definitions
SKILL SAW: A portable cutting tool used to make boards too short.
BELT SANDER: An electric sanding tool commonly used to convert minor touch-up jobs into major refinishing jobs.
WIRE WHEEL: Cleans paint off bolts and then throws them somewhere under the workbench with the speed of light. Also removes fingerprints and hard-earned calluses from fingers in about the time takes you to say, -----------. Will easily wind a tee shirt off your back.
DRILL PRESS: A tall upright machine useful for suddenly snatching flat metal bar stock out of your hands so that it smacks you in the chest and flings your beer across the room, denting the freshly-painted project which you had carefully set in the corner where nothing could get to it.
Channel Locks: Used to round off bolt heads. Sometimes used in the creation of blood-blisters.
HACKSAW: One of a family of cutting tools built on the Ouija board principle. It transforms human energy into a crooked, unpredictable motion, and the more you attempt to influence its course, the more dismal your future becomes.
VISE-GRIPS: Generally used after pliers to completely round off bolt heads. If nothing else is available, they can also be used to transfer intense welding heat to the palm of your hand. (Also, commonly called "Channel Changers" on TV's of the 1950's with knobs that were stripped out or lost when you were fighting with one of your siblings.)
OXYGEN/ACETYLENE TORCH: Used almost entirely for igniting various flammable objects in your shop and creating a fire. Also handy for igniting the grease inside the wheel hub out of which you want to remove a bearing race.
TABLE SAW: A large stationary power tool commonly used to launch wood projectiles for testing wall integrity. Very effective for digit removal!!
HYDRAULIC FLOOR JACK: Used for lowering an automobile to the ground after you have installed your new brake shoes, trapping the jack handle firmly under the bumper.
BAND SAW: A large stationary power saw primarily used by most shops to cut large pieces into smaller pieces that more easily fit into the trash after you cut on the inside of the line instead of the outside edge. Also excels at amputations.
TWO-TON ENGINE HOIST: A tool for testing the maximum tensile strength of all the crap you forgot to disconnect.
PHILLIPS SCREWDRIVER: Normally used to stab the vacuum seals under lids or for opening old-style paper-and-tin oil cans and splashing oil on your shirt; but can also be used, as the name implies, to strip out Phillips screw heads. (The Phillips screw was brought to market by Henry F. Phillips of Portland, Oregon and first used on the1936 Cadillac. Now you know who to blame for those stripped out heads. Yes, Phillips Lake near Baker, Oregon is also named for Henry Philllips.)
STRAIGHT SCREWDRIVER: A tool for opening paint cans. Sometimes used to convert common slotted screws into non-removable screws and butchering your palms.
PRY BAR: A tool used to crumple the metal surrounding that clip or bracket you needed to remove in order to replace a 50 cent part.
PVC PIPE CUTTER: A tool used to make plastic pipe too short.
HAMMER: Originally employed as a weapon of war, the hammer nowadays is used as a kind of divining rod to locate the most expensive parts adjacent to the object you are trying to hit. Also very effective at fingernail removal.
UTILITY KNIFE: Used to open and slice through the contents of cardboard cartons delivered to your front door. Works particularly well on contents such as seats, vinyl records, liquids in plastic bottles, collector magazines, refund checks, and rubber or plastic parts. Especially useful for slicing work clothes, but only while in use. These can also be used to initiate a trip to the emergency room so a doctor can sew up the damage.
SON OF A BITCH TOOL: Any handy tool that you grab and throw across the garage while yelling 'Son of a bitch' at the top of your lungs. It is also, most often, the next tool that you will need.
DAMMIT CLIP: For us old timers, a clip used on carburetor linkage that was easy to remove but almost impossible to put back on. When it went flying to who knows where, the mechanic would say: "Dammit, where did that clip go". We learned a lot about baling wire from that experience. Usually found months or years later by pure accident...

Didn't Outboard Marine have a plant in Peterborough, Ontario?
They made good products.
Cheap 2 stroke lawn mower engines that wouldn't die, for instance.

Sorry Ole, for I have to stick with Tesla on the ALTERNATING CURRENT. https://en.m.wikipedia.org/wiki/Alternating_current
A two stroke outboard motor with magneto running at 3600 RPM has a commutation rate of 60 Hz same as the AC 60Hz line freq. When I was a repair technician for 7 years with Outboard Marine Corp, I got to see a magneto instrumented in a lab with scope leads to enable viewing the voltage and current traces during the magneto cycle. During the 1st step, N-S PMs passing poles 1 and 2 of an E frame armature there was induced a forward current and a positive voltage of up to 450V with a current trace clearly showing the knee of the BH curve indicating the saturation of the iron at peak positive induced voltage/current. As Kone pointed out, this is a short circuited primary winding cause one end of winding is frame grounded and the other end of winding is grounded via the closed breaker points. As you pointed out, current does not like to be stopped and electrons do have inertia so the condenser acts as a shock absorber to take the current surge at point opening and also prevent arcing in the breaker. the accumulated charge in the condenser at circuit opening is up to 450VDC positive. When the breaker points opened there was a straight down, negative going high magnitude negative spike off scope scale. Remember that when the breaker points open the PMs are now inducing a reverse polarity voltage and current into poles 2 and 3 of the E core. I guess that Outboard Marine was correct in using the E frame coil stator for it produced an excellent and powerful ignition source. Since then we have graduated to the Capacitive discharge type of ignition systems.

Hi Norman, Mick,
"...a reverse current is being induced into the iron core coil with the reverse polarity."
The current continues in the same direction while the voltage or tension changes sign. The current can't be stopped or having its direction changed in a jump as it is always continuous. It would be like immediately stopping or changing the direction of a running flywheel. The force required or given off is like the voltage when speaking coils. The voltage or force will be of infinite size if the change happens in an instant. The current starts decreasing from whatever value it has at the disruption. Only how fast is related to the size of the induced voltage (u = L x di/dt) where u is the voltage, L is the inductance of the coil, i is the current and t is time. di/dt is the slope of the current.
Regards
Ole

Mick, first envision a North-South magnetic poles embedded in flywheel. When the North-South magnets bridge the first two poles of the stator (rotation) a forward going current is induced into iron core coil and at same time charges up condenser to max. Important note here is that the impedance of coil is LC matched to the value of the condenser. When the North-South magnets move over to the middle and last poles, breaker points open and at same time a reverse current is being induced into the iron core coil with the reverse polarity, the condenser discharges through coil windings to frame ground. With the condenser being charged via the forward going current, 1st step, when it discharges into coil a reverse current is being induced by moving magnets. In effect you have opposing currents, opposite polarity, (BUCKING-OPPOSED) which cause a miniature magnetic flux annihilation event and a MAGNETO-ELECTRIC, micro EMP event. That is the reason the old magnetos had such a powerful spark even when you turned them by hand at super low RPM. I worked on thousands of them on my magneto test bench. Norm

Norm,
So this is the same effect from the 3 pole magneto you showed us, when the cap discharges during the collapsing flyback pulse and compresses the delta?
Were three poles used in parallel in order to make sure the iron was fully saturated even at low speed in the old magneto?

Your quote, feed it a reverse potential as voltage is maximal peaking and you have a mother of an EMP neutral spike on your hands ! Yeeeeeeaaaaah! Hector my friend, you got it exactly right. In all my experience with old time magnetos, this is exactly how the conderser discharge through the primary windings happens with reverse polarity. Bang, you get a sharp crack spark discharge in the bright blue wave lengths. Not a measily orange spark without any zip to it. The 5HP compressor, EMP test I did works this way.

If you short a coil current becomes maximal voltage stays lag at zero upon max core saturation , then at short cut off ,voltage becomes leading and maximal as current drop to zero ... basic RF neutral spike dynamics !

Hi Mick
"would require shorting to saturate the core from passing a magnet"
Did you mean:
"would require shorting to saturate the core from a passing magnet" ?
I don't know something else?
Also wouldn't a shorted coil become rf transmitter not so much an antenna?
Anyways still confused but just half way confused now..
