flip a coil: Is Levitation Real? My Coil Demo Shows the Answ

In this quick bench session I stacked donut magnets and coils to chase levitation. You see the heat, the push-pull, the pole flip, and a bit of electricity coming off the coils. No clean voltage numbers but the magnets definitely floated for a second.

Key takeaways

• Magnets levitate when like poles face each other over the coil stack
• Flipping the middle magnet creates a centered pole that stabilizes the setup
• Coils get hot fast when magnets get too close
• The levitation electricity coil demonstration produces a small boost you can feel
• Simple stacking with hot glue and careful flips is all it took

I grabbed a few donut magnets and some coils that have been working pretty well. Stacked them up, felt the heat right away, and yeah — the top one started to levitate a little. That's the whole point. We want the magnets as close as possible to the coils without touching.

Flipped the middle magnet to create a pole in the center, then flipped the top disc and boom — levitation effect. I felt it through the whole stack. Plugged the multimeter in but didn't catch clean numbers before it got too warm.

Bench notes: Coils secured with hot glue and Gorilla Glue. Discs stacked bottom to top. Magnetic push was strong enough to lift and center. Heat built immediately. Small electrical output noticed but no steady voltage reading.

If you're into pulse motors or just messing with magnets, this is the kind of quick experiment that gets you thinking.

From the spoken experiment

The following notes stay close to what was said in the video about flip a coil:

> hello uh and welcome to my demonstration hopefully this works I mean these coils have been working so far very well um I haven't fixed them to uh uh with uh Gorilla Glue hot glue gun adhesive and I'm going to do this disc and the way it's going to go is that disc is going to go on the bottom of wherever I'm going to put it then this disc is going to go on top of that and then this disc let me get it real quick this disc will go on the top of that like this oh I don't already feel the heat oh my god dude it's kind of levitating there and that's the whole point we want the magnets to get as close to those coils as possible we got a little a little bit of a boost um what I'm thinking might happen if we got enough space is just this you flip this one and then you put the coils back on and there'll be a pole in the middle so they'll be centered then you take this disc and you flip it over so…

Builder checklist

• Confirm trigger/sensor timing before chasing higher voltage
• Watch heat on coils and transistors during longer runs
• Record voltage and behavior at each change (one variable at a time)
