Made by the Jam Handy Organization during WWII, training film is about the aircraft magneto -- an engine driven electrical generator that uses permanent magnets and coils to produce high voltage electricity to fire the aircraft spark plugs. Aircraft magnetos are used in piston aircraft engines and known for their simplicity and reliability. The film employs impressive hand-drawn animation as well as stop motion animation techniques similar to those pioneered by Ray Harryhausen.
Opening titles: Scintilla Magneto Division of the Bendix Aviation Corp. presents The Aircraft Magneto Part 1: Theory Of Operation Of The Four Pole Magneto (:06-:32). Various machine pieces and screws move around and piece themselves together (:33-1:16). Different types of aircraft magnetos. A man places an aircraft magneto down. Magnets and wires are then placed down. A steel magnet is used and attracts iron. Each magnet has poles, north and south, opposite poles attract. Lines of magnetic flux are explained. Iron nail is stuck to a magnet (1:17-3:55). Iron nails are known as temporary magnets. Lines of flux. Magnet and wire (3:56-5:27). Wire and a magnet are near one another and explained with how currents flow. Lines of flux in the magnet and one line of wire. Diagram explains current flow (5:28-7:20). Using a stronger magnet is explained along with more coils of wire as flux linkage increases. Wire carries a current in an experiment (7:21-8:30). In the experiment, when the wire is cut, field around the wire disappears. Magnetic field and flux linkage is shown and explained (8:31-10:27). Lenz's Law is explained with a title card, a law stating that the direction of an induced current is always such as to oppose the change in the circuit or the magnetic field that produces it. A diagram shows how this works and explains it (10:28-12:15). Soft iron core, two magnets that can be rotated, iron shoes, a diagram shows how these items together will move the flux. Full register position of the magnet (12:16-13:28). Diagram shows magnet turning. A coil of copper wire is the primary coil. Static flux. Primary flux and static flux with the resultant flux (13:29-15:26). Primary wire is cut causing the flux to stop; diagram shows this (15:27-16:21). How a magneto can work is shown in a diagram and explained. E-gap explained (16:22-18:10). Inside the magneto as the flux goes is shown via a diagram. Flux surges (18:11-19:42). Inside the magneto diagram. Break in a circuit causes a flux change.The current and the gap are shown and explained (19:43-21:11). A condenser is connected. The condenser is shown on a diagram and explained. Magneto is ready for use (21:12-22:14). Aircraft ignition system with two magnetos, spark plugs, and switch. How voltage works is explained in a diagram (22:15-23:49). Aircraft magneto as it is assembled. Rotating magnet, crankshaft. Soft iron. Thin sheets of soft iron. Pole shoes and pole extensions. Primary condenser. Nickel foil plates (23:50-25:39). Coil assembly in a magneto is shown and explained with real parts. Breaker assembly, spring and breaker points (25:40-27:00). Distributor block. Diagram inside a magneto as current moves towards distributor. Dots are shown to represent a spark. Magneto. Plane takes off from a Carrier. U.S. planes in the sky (27:01-29:46). End credits (29:47-29:55).

To whom it is for showing us these wonderful films I personally want to thank you

This is great. There is some archaic terminology (the use of the word condensor instead of capacitor, tension instead of voltage, and not using other modern units and formulae related to inductance). The fact that an alternator or magneto is a huge source of broadband radio frequency noise is also of huge importance to aviation mechanics watching this. And yet I feel few modern training materials are this clear or effective.
Well thought out films with clear explanations. Modern training films can learn from these.

Back when sense had value.
When things were engineered & built to last.
This was from a day when we manufactured goods in the US .
"Made in the USA" typically meant a higher standard of quality.
Besides the jobs of manufacturing parts & products as well as engineering them was an entire field of workers to service & repair them.
TV or vacuum repair men. Stoves, refrigerators, washer repair men.
Now everything is engineered to fail.
Products are made as cheap as possible.
Everything is disposable now. Even the employees.
Very little is built in the states.
It's how they want it. It keeps wages down
Keep up the great work Periscope. Thanks for posting great video's

I like clarity if this video, amazing stuff !!
Nice.Without magnetism we would be still in the stone age.
Guess what Lenz’s Law is related to?
Does “An Object in motion remains in Motion, and an object at rest remains at rest, unless acted upon by an outside force” sound familiar (Newton’s First Law).
This is just another manifestation of that property, where the System (wire, or coils of wire), wishes to remain “without current” when no current is flowing, but once an outside force acts upon it to induce a current, the wire now wishes to retain this current.

These are awesome, thank you!
One of the most mysterious forces in the universe. We are still far from completely understanding electromagnetic/weak interactions.
Excellent ! Thank you. Can someone provide reference/access to “Part 2” of this Aircraft Magneto Training film series ? Thank you.
I have a feeling my internet connection would be a lot slower if magnetism didn't exist.
Love the stop motion
I got the "point" of electric stuff after watching this film
Great film thank you for sharing it.
Will there be a part2?
"how a magneto works, oh is this for like engineers or whatever"
"a magnet has two poles"
"nevermind"
Most are much smaller, but mags are still used nowadays on the vast majority of piston aircraft engines.
Anyone under 30 y/o watching these with me?
me, 16
Me, 26

Any possible way to stop putting up that extremely annoying PF# time hack?? Can you at least make it very very small in a corner or something? It really isn't necessary to begin with, its just something you do. Just your logo in the corner would be more than whats needed.
Theres your tesla motor.
Aether energy from static electrical earth.
