Magnetic Levitation Using Hall Effect Sensors.

[@wilurbean]

Built one of those automatic floating magnets in a lab class. You don't really need a thousands of times per second a refresh in the 100s of times a second is more than enough. It's really a demonstration of PID control

[@mrbrown6421]

In case someone was wondering: "A PID (Proportional - Integral - Derivative) controller is an instrument used by control engineers to regulate temperature, flow, pressure, speed, and other process variables in industrial control systems."

Isn’t it just bang-bang control in the Hall effect sensor + op amp to drive a mosfet gate for the electromagnet?

The application possibilities! Thank you for sharing and educating! ⭐️⭐️⭐️⭐️⭐️

Very cool! I want to learn more about electronics and magnets so I can make one. Before I found your video, I bought two off of Amazon. One has a moon that levitates and lights up. The other one levitates and lights up a light bulb,

I like those Hall effect turntables :)

[@leesandhoefner6697]

Would love that on my desk for a conversation piece and for blowing minds.

[@beakytwitch7905]

Damn good ! I'm going to have to build one of these... :-). ❤😂😊

[@Coolbreeze72]

That's awesome 👍😎

You can make a stable passive system using pyrolytic graphite. No need for spinning etc. Great diamagnetic substance and so no need to worry about Earnshaw’s theorem.

the upside down one, what happens if you accelarate a car with this in it...

[@The1Corrupted]

Magnets. How do they work?

[@GrantsPassTVRepair]

Good question, but know one knows for sure.

[@3rdalbum]

I think @The1Corrupted was referring to the Insane Clown Posse song "Miracles"

[@GrantsPassTVRepair]

@Vonderbach We only have theories about the nature of a magnets and electricity, and we know how to predict their behavior and work with them, but our knowledge of magnetism and electricity is still limited to theories.

Without energy loss is it possible?

[@jevontejohnson6605]

That’s how the pyramids were built buddy !

You have literally just created a Future😳 Barber Shop's pole 💈.. But, I'm sorry, you can go Nowhere Near the shop.. I really don't trust a Mr.Induction walking around in There.. 😅

Bismuth is easier.
