Brilliant explanation! These old videos really are the best learning resources.
I like how they start: "In the old days..."
Probably the best explanation of electric motors I have ever seen.
The quality and clarity in describing the function of components in these old films is really unsurpassed.
The US Army really knows how to make great educational videos. Every army training video I've watched is concise and articulate.
The one with the wood gun that explains diff small arms is great. Simple but functional.
11:08 "but they never succeed". Armature is my spirit animal
Fascinating amounts of detail! This video has insane production value for it's time
Hell way better than today
Their presentation says a million words.
I love the neon tubing as the electric field, awesome presentation.
Truly, old is gold.
All old educational videos are exceptionally brilliant!
It was these videos and the G.I. Bill that got us into space.
The very best educational material is the oldest!, these videos are way better teachers than any program in modern schools!
All educational films should be like this. All of them.
Although this might lead to some rather more awkward moments if we use films like this to explain the birds and the bees.
hatsoff to the people who made this video no 1 can explain like this...understood everything made things so simple....
and all this techinal graphics without a computer.Great artists
they couldn´t explain it better!! thanks a lot!
WHAT a very educational and good video. Thanks a lot for uploadin this. Excellent
Till now the best explanation I have seen.
Incredible. Thanks for sharing this knowledge. I am very grateful!
always old schools is better than new now schools that is amzing thanks
Old is gold.
The difference in quality education makes difference in quality engineers
Very well explained and informative. Better than MIT explanations
Thank you for sharing all these videos... Very AWESOME.. Knowledge is priceless..
GREAT! and so the making and devices to explain it!.
Very well explained and informative. Love these old informational videos...
Excellent presentation
Thanks. This helped me fix my kitchen blender, desk fan, and Tesla car.
Such a nice humor you have.
Brilliantly describe, mind blowing, best one❤❤❤❤
I think it's easy to see why this video has zero dislikes.
This video is incredibly well done!
I love thses videos. I wish I could find all of them.
Such an amazing explanation I love it haha it helped me alot! thanks :)
Love these, so informative
amazing video 💕💕💕💕💕
Love it.
Good video, but the poles of an electromagnet are not ON the wires. The magnetic field lines pass through the middle of the loop, at a right angle to the current, so it's as though a bar magnet is going through the middle of the wire loop.
Yes i noticed that as well
In the days when a PowerPoint presentation required the introduction of a full symphony orchestra.
Superb
THANK YOU
great video, except that the poles of the electromagnet are a bit misleading as the magnetic moment is perpendicular to the plane of the loop.
This. I don't understand how most of all technical education videos from all kinds of even the most professional producers (these old black and white ones tend to be the best, but even these...) have that much crucial omissions and even outright mistakes.
Besides the error you mentioned, this also failed to mention that in real-world usage, coils are used instead of single loops, and also the overall structure of iron cores - both the armature and stator - was completely omitted to show, which would be quite essential in order to efficiently route the magnetic flux into the place where the two perpendicular ones (stator and armature ones) meet and create force between each other.
Also, I would have liked to have at least very simply calculation example of torques and currents with voltages, turns, core sizes, etc. In case this was meant to be theoretical. In case this was meant to be practical, I would have liked to have instructing to replace brushes, bearings, and finding faults on coils.
Very nice and wil help me for my physics class even though it was made in 1957 XD. But why is there a 2 min blank part at the end of this video, I thought there was going to be more but it ended at 12 min.
Nice
i love the min 14:03 is so informative
Army training; breaking it down barney style since 1775! ;)
It was well explained but you must not have watched many MIT lectures. There is a big goof up in this video's explanation, when you have a loop of wire with current in the wire doesn't get a north and south pole, the field lines are always at right angles to a conductor not emanating from them.
thanks allot
WOW
we human are so clever ,im starting to think that we human is the alien we were looking for ,,,our brain is the key
obviously the guys who sang 'f##### magnets how do they work' have never seen even one of these videos
The first line in the video is "In the old days,"
Excellent explanation now I can get full marks in tomorrow's test

+Wansufyan Mudeng yes?
No mechanics understand this now a days, even the super expert experienced ones...
I love the format of vintage US Army training videos but... this one contains a major flaw!
Saying one side of the loop is the S pole and the other one is the N pole is not right. A current carrying loop of wire effectively becomes an electromagnet with a magnetic moment normal to the current loop.
If you want to think of the loop as a magnet, it should have the axis punching through the center of the loop, have (almost) zero length and direction determined by the direction of the current in the loop.
As a result the loop won't align with the magnetic field as shown, instead it will place itself at a angle of 90 degrees.
and how much for a year at MIT?
I’m still confused but I do think I know way more than I did. Something about never reaching continuity and using magnetism and pole reversal to get rotational movement. Dope
I just watched that Insane Clown Posse video just to hear that godawful line!! It brings tears to my eyes from laughing so hard. I will never look at a relay the same again after that song.

Let the U.S army teach science at schools instead of fighting😅😅

convert? can't consume
animation in 1957????????????
I'm a big fan of these old film but this video is totally blunder as it's shows wrong position of North and South pole of the electromagnet.
It is not the two side of the coper winding that becomes two poles.Actually two poles occers in the perpendicular space of the winding.
Suiiii
motors don't produce energy, they consume it ;-), but ya old videos rule, makers of these old videos invented that shit.
its amazingly sarcastic how this video starts with "IN THE OLD DAYS"
lol ! motors PRODUCE enery (mechanical energy). by consuming electrical energy.....and as u said it does not produce energy then wats the purpose of it :D jus for timepass?:)
