The Amazing Eddy Current

Eddy Current is awesome and awful at the same time! Cherish it!

It would be pretty awesome if you support ElectroBOOM at Patreon:

Below are my Super Patrons with support to the extreme!

Regarding the transformer: the eddy voltage is so low that even the iron oxide on the plates is enough resistance to top current from forming. The weld of course has lower resistance but since its pretty much a high resistance iron wire it is not so bad to be worse than leaving the plates loose (because they vibrate like crazy when under load). Still if you hook up a huge load to the transformer and look at that weld with an infrared camera it will indeed "light up". also along the same idea a solid aluminum pipe of the same size and weight will make the magnet fall more slowly than the foil roll.

0:58 even in an experiment not involving high voltages, Mehdi still manages to create an explosion of sparks.
I love it.

[debasmitdey]

0:58 the spark was so perilous that even the clock moved 20 seconds forward XD

I learn and I laugh without fail with every upload. Thanks ElectroBoom! 🙏

"I created a voltmeter... that's drawing ten amps."
LOL!

[jbvmpsmtr]

6:40 "I created a voltmeter... that's drawing 10 Amps" 😆🤣
You're the best! 👍

I am a level 3 Eddy Current inspector. We use eddy currents to detect cracks in aircraft.

I probably would have had better grades if every teacher was as interesting as electroboom

6:00

This is my favorite electroboom moment because the way he says “holy shit” is just too funny

[joshuareynolds]

The spark at 1:00 caused the clock to jump forward 13 seconds

The larger of the two transformers you showed here is a microwave oven transformer (MOT), which is designed to step mains AC up to around 2000 volts for the magnetron circuit. The pair of welds across all the layers of the MOT core do serve a purpose beyond being structural:
The ground connection for the high voltage side is the MOT core and its mounting plate. The ground terminal of the magnetron is connected to the MOT through the isolation capacitor (to filter out any stray DC) and the metal frame of the microwave itself.

This simplifies wiring a little, since only one high voltage lead needs to go all the way from the MOT to the magnetron. Another function is to ensure that any stray current induced inside the oven itself is immediately grounded. If the layers of the MOT core were not welded together, the induced high voltages would spark or arc between layers, overheating and corroding them.

1:00 he discovered time machine without him noticing

0:59 When the explosion happened the clock skipped 10 seconds. Am I the only one who saw this?

5:36 It's amazing to see how loose turns of coil, cake into a temporary compact coil (while energized they get atracted among them).

[arfyness]

I never understood superconductor levitation until you explained it like that. Thanks!

I would say that the Microwave transformer, being one that works in high power ranges such as 800-1000 watts, creates a loud and noticeable 'humming' noise in the 50/60 Hz range. The MOT is welded together and coated with resin to suppress those humming noises. It is cheaper than clamping and would save space. Naturally the eddy current losses would be higher compared to other laminated iron cores but probably not enough to compensate for the acoustic noises you would get from them otherwise

Damn, he was making video from 10:30 to 5 . Amazing dedication

Mehdi current: the current measured when Mehdi electrocutes himself.

@01:00 the short circuit affected the time ! Watch the clock jumping 9 secondes ahead !
