Trying to See Rotating Magnetic Fields

Here I try to show you the actual magnetic fields rotating by 3 phase AC.

"This piece of SHEET" Loved that! HAHA

[fudgesauce]

Mrs ElectroBOOM: "Mehdi, why are you squatting up and down like that?"

Mehdi: "Oh, this? Don't worry, it's just a phase I'm going through."

[JeffGeerling]

There is a lot of SHEET in this video.

8:00 This weird freaky thing is actually the most helpful 3 phase explanation I've ever seen. Up until now, I could never quite get my head around how the 3 phases worked together to make the motor turn.

3-phase Mehdi is a must for the Wallpaper Engine!

[hamizchokhandiwala]

The way he says "oh now it's on fire" so calmly is like it's an everyday thing for him 😂😂

[LabCoatz_Science]

Great video Mehdi! My best guess is that the film takes too long to "decay" between its magnetized and non-magnetized states, so you can't see the changes. Love the LED demo, that was an excellent visualization!

0:12 I’m now convinced this is precisely how all motors work

[MohamedWaheedAtef]

@3:24 "this piece of sheet" 😂

[PlasmaChannel]

I see you've got acrylic fever, Mehdi? :D The only known cure is MoRe AcRyLiC!
Absolutely epic ending.

[Miata]

$3, 000 worth of fancy power supplies make the LEDs go "Blink."
Lovely

[GodFlameTheIronChest]

I love how he slowly went from "piece of sheet" to "piece of shiz" as he's getting more irritated

[gabrieldayan]

It’s kind of like the lights at the entrance of the theaters - like how lines go around but it’s just light bulbs turning on and off at the right times that gives it that illusion

[Geniusinventor]

The most important part of the video 7:50 . It's healing me psychologically

[chriswu]

The last 10 seconds of this video were seriously the coolest trippy thing I've ever seen!!! Keep up the good work man!!!

[yuvalkaroly]

I work at a super high precision brushless motor company and have been having a lot of fun watching your videos on rotating magnetic fields! Let me know if you'd ever like a sample maybe I can convince my boss to send you one HA

The song during the blinking LEDs at 6:55 is Follow Me by Andrew Langdon

[Graham_Wideman]

Mehdi -- I think you're right at 3:15 about both North and South appearing as solid dark. However, you might be able to "bias" the field seen by the sheet. For example, if you positioned North poles on the other side of the sheet (at some adjustable distance), than at the sheet's location you might get either strong field lines, or minimal field lines, and thus dark or light pattern on the sheet. But also the rate of change (rotation) probably needs to be far slower than 45 Hz.

FYI I was perfectly happy with the psychodelic kettle drum visualization. And it was apparent that you really put yourself into it.

[DonnyW]

Hey Mehdi, I was thinking 🤔, instead of wrapping the film around the motor, what if you cut a hole the size of the motor in the film then poked it through? That way maybe you could see the field lines in cross section.
