So sky scrapers should have aluminum escape tubes where people ride down on strong magnets?

Who is Eddy Current?
it is not primarily about resistance ,the area has a huge affect on the eddy currents produced and by using a thicker foil you just increased the area in which the magnetic fields of the magnet were in-contact with the foil ,hence higher eddy currents were produced .

+SoraWisdom Thanks for the compliment, but I really learnt all of this by watching an episode of extreme engineering on discovery Channel 😂😅 EDIT: Here's a National Geographic video on the subject: https://youtu.be/F66pBxgFNBI

+SoraWisdom If all the multiple backup generators and emergency brakes (they have traditional friction brakes as a backup) fail, you would be unable to stop the car at command but the rollercoaster is designed to not let you die - you would just go back and forth on the track until you would eventually stop somewhere.
SoraWisdom (2 days ago)
+Alessandro Celoria wow i never knew that. so a power failure could mean death?
Alessandro Celoria (2 days ago)
No unfortunately - you would need way too much power. However this technology is already used to do the opposite - rollercoaster brakes function using eddy currents! (There are electromagnets on the car and aluminium plates on the rails)

Why does increasing the amount of aluminium used *decrease* the resistance? That seems a little counter-intuitive to me. Someone help me out?
Delta B (6 days ago)
The aluminum layers DO add together to make one thick current path, but the thicker a conductor, the easier it is for it to pass current, so the resistance goes down. In the same way, a meter of 1.5mm^2 16 awg wire has higher resistance than a meter of 4mm^2. 12awg wire. The thicker the conductor, the less the resistance.
Millar (7 days ago)
+Delta B That's still confusing me a little. I would assume that because they're not insulated from eachother they would all stack to produce one thick path for the current, increasing the resistance. That then leads me to think that the thicker the path, the higher the resistance (which is true but isn't demonstrated by this example, of which I'm clearly missing something from!)
Delta B (7 days ago)
Because the aluminum foil layers aren't insulated from each other. Each new layer that gets added gets connected in parallel to the other layers, making more paths for the current, and lower resistance.

Well, if the voltage in the spool wire is 120 volts and you run 36.5 amps through it, it theoretically generates 4 380 watts of heat (some of the energy turns into vibrations as can be seen in the video), no wonder the spool gave up :D

I designed, “A voltmeter drawing 10A”, absolutely classic. Your humour is rare and fantastic and I am sure very well appreciated by possibly as many as half a dozen of your viewers. Most of the others of course just laugh, not understanding that the joke is on them. The more I watch the more I appreciate the considerable talented and dedicated effort you make to plan & produce these videos. Your foil covered paper tube was highly significant. I saw that and could hardly believe it, why didn’t it work. It didn’t take long and I wanted to see you use a proper aluminium tube, I was considering the impedance change from the single layer to the overlap and wondering how the interface was acting. Then you sort of answered it. But, does a single layer not work due to its layer thickness being too high an impedance or is it because of the much higher interface impedance of the joined edges of the foil relative to the Foil z? Perhaps you can bend an edge at 90 degrees out and wrap the foil around the paper tube and fold the opposite end 90 degrees out where they meet and then fold the 2sticking out edges together overlapping them several times to make the best (lowest resistance possible) termination and try dropping another magnet through it to see if it’s the wall thickness that matters or the uniformity of the current around the circumference in the foil. I have seen many transformers with welded laminations but almost always they have effectively had a slot cut along them and the slot in-filled with weld (obviously it’s just the press that has a notch in the die for each lamination).The thought that this is something electrically clever is exciting but I have never found any such evidence and if there was then everybody (almost) would be doing it so I believe it’s just to simplify mass production. You have already talked about diagonal wires apparently shorting laminations in induction motors and I remember old gramophone record players that had copper wires / copper bar at about an 1/8 inch dia across the laminations - 2 bars , of copper on opposite sides and non-symmetrically positioned but both transverse to the laminations.

Could you make a coppercoil and throw a magnet down? But the tube should be 1,5m long
HPD1171 (14 days ago)
the welds on that transformer would not really contribute to losses because the loop they enclose is perpendicular the path that the eddy currents would take just like how the individual plates are also placed perpendicular to the eddy current path
Wdowa94 (15 days ago)
I have found some welded transformers, but only in audio devices. Maybe it's welded because of the ground noise?

your breaker didn't trip probably because you may have inverse time breakers in your home. Inverse time tripping is a characteristic of circuit breakers in which the breaker trips in more time with lower overcurrent, and less time with higher overcurrent.

so can you super chill the aluminium tube to hold a magnetic object or will that not reach the needed values?

Welding the core plates together only to prevent unwanted noise from core plates becoming unlaminated and vibrating.. more likely in kitchen appliances to keep them from making noise ..old high intensity discharge lamps like in a warehouse have a distinct buzzing sound from this very thing..

I guess your breaker didnt break because the transformer took huge amounts of current but barely any power because of the horrific power factor? Would be a bad breaker though, if it worked like that.
Chuckiele (1 month ago)
+jim halcom Well yeah, but that slow at that huge current?
jim halcom (1 month ago)
breakers are designed to delay so that the high torque and starting current of most power saws and heavy tools can start up without tripping the breakers. so that is completely normal Because of the delay of breakers it is nessesary to put fast blo fuses close to the electronic equipment
