In this video I'll try to test 3 ideas how to make a coil gun more powerful. 0:08 Material Type of Projectile 1:43 Both Side Acceleration 7:44 Temperature
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.
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
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!
Hi. I also have a new video: coil gun new test - The safest coilgun (50 Volt!) czcams.com/video/TMsLIAmuuO0/video.html czcams.com/video/0nMyv83_ycM/video.html
Finally! Somone actually tested pull and push from each coil, thank you so much for making this video!
Hi. It's really super cool! I also have a new 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
Do you have a less blurry photo of the H-bridge schematic?
Awesome, keep up the good work!
I'm hoping for bullet like speeds in the future! 😋
How much amps did u use for your coilgun ?
This was so helpful 👌
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.
