Hi. It's really super cool! I also have a new video: coil gun new test th-cam.com/video/TMsLIAmuuO0/w-d-xo.html th-cam.com/video/0nMyv83_ycM/w-d-xo.html
The reason the magnet was slowed when falling through the aluminium tube was because it was generating an eddy current. As the magnet fell, it was creating distubances in the electrons of the metal pipe, which generated a brief electric field, dispersing its kinect energy into electrical energy. This can only happen to a noticable degree if the tube is complete, or of substantial mass. If you cut a slit down the length of the tube, you will break the "circuit" and the eddy currents produced will be MUCH weaker. This is better than using the plasic tube since metals have lower friction co-efficients and have more wear resistance. Hope that physics break-down helped.
This vedio helps me a lot. If it is possible to make a video to show how to choose the coil(width , length , radius, turns) of the coil gun with different voltage and different capacitors. Thank you!
the magnetic field doesnt go away completely after the coil is turned off either. the B field decays quickly but its not insignificant. if a magnet was used, it would be more strongly attracted to beging with, allow switching, and negate some residual drag from the non-instantaneous drop in voltage

Hi. I also have a new video: coil gun new test - The safest coilgun (50 Volt!) th-cam.com/video/TMsLIAmuuO0/w-d-xo.html th-cam.com/video/0nMyv83_ycM/w-d-xo.html
Finally! Somone actually tested pull and push from each coil, thank you so much for making this video!

Thanks for explaining.
have you tried to shield the coils with ferromagnetic material to reduce reluctance by a lot , increasing magnetic flux?

The parameter of mine is 420V and 560μF
Awesome, keep up the good work!
I'm hoping for bullet like speeds in the future! 😋
Do you have a less blurry photo of the H-bridge schematic?
A bit curious what happens if the regular coil is replaced by a step up or step down configuration tesla coil type do you think that could/would work?

This was so helpful 👌
How much amps did u use for your coilgun ?
👍попробуйте намотать катушку проводом 1мм и разряжать на неё как можно больший конденсатор
А если взять катушку длиной метр и диаметром 10 см, и конденсатор на 2500В, то реально рекорд получить.
do you have a aprt list

So much bullshit in the first point. You cant "push out" a proejctile OUT of a coil.
He's using a magnet as a projectile.
Magnetic repulsion.
