50 Volts, 3 Amps! That coil is going to get very hot very quickly!
luckily it is more or less instantaneous so with right gauge wiring it might not heat up that much. but i guess this depends on rate of fire (% on time of the coil)
It shows just 14 V on the display though. That's still 40 W of heat (pretty much for a coil that size). But since it only need to be turned on a brief moment during a shot, that will not be an issue even at 150 W (50 V, 3 A) of heat (it will still need several seconds to get a significant temperature rise)
@@Speeder84XL I guess I misheard 15 as 50. Which does explain why there was no visible smoke.
@@BrianG61UK Yes, but he does write "50 V DC to it" as text as well, at 0:22 in the clip. Which is a bit confusing, as the display on his power supply shows 14.
Yes - during the demonstration when the steel bar gets "stuck", he runs it for quite a bit of time as well (much longer than what's needed for a shot).
So at 150 W, it would at least get hot enough for him not being able to hold it with his hands, maybe even start melting the plastic tube in the middle, haha
@@BrianG61UK Another interesting point, is that if it does heat up significantly, we would either see the current decreasing over time or the voltage rising (depending on if he run the supply in constant voltage or constant current mode) - as copper changes it's resistance quite a bit with the temperature.
We even see that now as he apparently run the supply at constant voltage 14 V and the current does decrease slightly from from 2.863 to 2.845 (indicating a slight temperature rise in the coil)
- but it would it would be much more at 150 W.
Make a loop of coils and you get a small hadron collider XD
but with iron bolts instead of hadrons colliding. So its a bolt collider
I don't think they are used to accelerate the particles. Particles are accelerated by 2 Ds (the part of the instrument is called D I forgot what the instrument is called) that are basically two "D" shaped objects(or two semicircular objects placed adjacent to each other that use alternating current to accelerate the particles. I think the big long ring is used to position the particles to crash into each other. Or maybe they accelerate the particles as well. I am not sure. But I am sure about the "Ds"
There's no greater technology than a massive hardon collider. Just think of the incredible new inventions we could erect. Just the thought of how many world changing applications are possible is discumbobulating. Deciding whether or not to use them for peaceful or military purposes is more than just a sementic question.
@kirito they do use magnets but they are very very power full, so mutch they need to be cool by liquid helium
What are hadrons?
I love how he failed to mention that this isn't bare wire. How many people wrapped naked wire around pvc and couldn't make a coil?
The wire is actually magnet wire that has a thin layer of insulation so that the coils can't touch each other.
I kinda thought of how is bare wire able to make that strong of an electromagnet instead of showing a insulated wire
yeah. enamel coated wire is used for electromagnets, since bare copper will just short.
Lacquer covered wire the same as if you would be winding a transformer.

What rare breed is this??
A youtube Short that I enjoied to watch?
That's definitely a first.
Exactly. No time wasted.
Exactly, no nonsense.
I don’t think rare breed makes this, they haven’t delved into coil guns quite yet.
@@Z3NITH_ sure, coil guns are power hungry and don't look to be viable at the moment. But have you heard about rail guns? They are pretty much same thing, but way too bigger, and those already exist.
@@GD-mw1kd i was making a joke about the company rare breed, they make triggers
Now take a serious lenght of pvc, several seperate coils with relays, charge them at the right time...bolt goes beyond horizon..now that would make a real coil/railgun...
How about reversing the polarity of the electyromagnet at the right time, expelling the projectile while it has some lenz magnetic charge? Has anyone done any real world testing with this?
@@alexanderg-p3z More power!! GRRRR 🤪
yes
would require the projectile to be magnetic and not just a normal bar of steel@@alexanderg-p3z
@@alexanderg-p3z Don't forget back-EMF will prevent the coil's field from reversing polarity instantaneously.
The field in the first polarity direction would have to collapse, then the field in the opposite polarity would have to form.
I did this for a collage project. Instead of figuring out when to turn it off, I just connected it to a huge capacitor and it worked fine. Just that it would take some time to charge.
How many microfarad and voltage??
Great video great Scott 👏
When your power supply is current limited at 3 amps
😂😂😂😂
So that's why I see the voltage drop when it is loaded. And that's why the wattage showed is the product of the new voltage and current
Why is it limited? How can he increase the amperage?
@@cam5816get a better power supply
Its kinda funny how many people confuse coil gun for rail gun. Speaking of which... make a rail gun next.
Basically the only difference between the two is the shape of the magnets propelling the rod right?
@KingCreeper85 no, thry are fundamentally different methods of magnetic acceleration.
Coil/guass uses wire coils which produce a melagnetic field when charged, this is set up to pull/push a projectile in sequence up to speed. No physical contact with the barrel.
A rail gun uses 2 conductive rails. The projectile is also conductive and completes the circuit across the rails. You then charge up capacitors to extreme voltages. When you release that energy via the circuit it will cause the projectile to be pushed down the rails until it is launched from the barrel.
Ding dong!
(Old school doorbell-tech reference.)
There recently was a story where a guy turned into a coil gun because he thought an unmentionable up his butt was non-metal and he went into an MRI. Not sure if it's a true story but that too was an application of this principle. A weird one for sure.
He had a buttplugg that said it was made of silicone but had metal in it
Link to Story pls…And his OF
@@Fee.1 Idon't have a link, it might just be an urban legend.
@@FHBStudio so where did you get the info that this was “recent” story

Phantom forces coilgun jumpscare
Actually pretty cool. Keep it up mate!
I know you guys won't understand what I'm saying, but holy shit is that the coilgun from Phantom Forces?
I thought it was too lol
EGUN USERS UNITE
IT IS INDEED LMAO
i think it is cuz its got the kosaku sight on it
Yesssss i was searching for this comment
Warhammer 40k fans discovering how bolters work
But bolters aren't coilguns at all?
They have a cased chemical propellant charge followed by chemical rocket motor.
Coil guns currently have a speed limit because the magnetic field doesn't dampen quick enough
There is a suspension system that uses magnets to thicken suspension fluid to go from soft to hard suspension suddenly, It had the same problem and they solved it by having counter rotating magnetic fields four to be exact.
This could potentially fix that limit and make high velocity coil guns
The suspension solution sounds very cool and interesting...
I’m confused on how the suspension system works or what exactly that is/does

They explain it better
I, and i can not stress this enough, LOVE THIS CHANNEL!
A normaly closed reed switch in the middle of coil would make this work quite easy.
bro used the phantom forces coil gun icon no way
Oh yes a PF player
For college? Did you calculate the varying rate of acceleration, speed and time to the center of the coil to coincide with the total discharge of the capacitor while also taking into account the varying reluctance of the coil as the bar moved through it?
Now i can make my self home-made electric bullet gun
This is how solenoids work too, but a bit simpler
Phantom Forces Coilgun lmao
love it now 3d print and build it next woot

Is that coil insulated? Because if not wouldn't the current take the shortest path?
Underrated video with a great explanation!
This is exactly how door bells work.
How does a coil work? Why do the electrons take the long route instead of jumping through all the touch points?
It is insulated wire
Magnetic force, potential and kinetic energy, velocity and concussive force
I did one accidentaly, i wrap beefy coil connected for a moment to AC mains 220v, i also added fuse. At first time coil swallowed small speaker magnet, normally it will turn inside like a motor, but this time i underestimated current and fuse blow almost ideal when magent was at middle...
Magnet shoot as crazy but happily struck wooden case of old TV leaving good dent "only"
Dude made a hand held rail gun!
Anddddd now you know how to make a particle accelerator
Could you just trim off the rims to the copper wire and keep it wrapped up the way it is? With out having to unwind an rewined it?

Awesome! Thanks!
real genius like electroboom!!!
Instruction unclear it truned into heater and burned my sofa 💀💀
but this wire is coated with isolator right?
Magnet wire or enamel coated wire
Very good explanation 🙏🏾🔥🔥🔥
Make a coil gun using only modified microwave transformers Lol, it'll be super powerful
Reminds me of the bore or a MRI scanner
It has to be coated wire. Otherwise the windings will short against each other and the electricity will take the path of least resistance. Which is the opposite of what you want to make this experiment work. If you try this make sure you use magnet wire.
Keep up with the shorts 👍🏻😊
ha! This video inspired me a while back, and now I'm actually designing a coilgun myself now
Every time I try something like this I end up shortcircuting a battery
Thanks, been teyin to make a particle accelerator
Very well explained.
Great, Scott!
Like the magnet on a claw machine
Yeah, that's how solenoids work!
The way he say wire just got me
That's all well and good but would the coil move back even if the rod doesn't touch the coil at all.
But isn't there energy stored in the inductor's magnetic field as it collapses? Doesn't that mean electricity will still flow for a bit after you cut power?
Only wind forward. Winding backward just increases the resistance with no increased strength. For multiple layers, move the wire to the back of the coil, and start winding forward again.
Why wouldn't there be increased field strength? Only the direction in which you go around the coil matters. Many machine wound coils are wound like that just neater so that there is no overlap. Moving to the back of the coil creates overlap and that horizontal part of the wire doesn't contribute to the field strength
@@laserdiode the direction of the wire winding determines the polarity. with 1 layer forward and 1 backward, you make a north and a south, which will cancel themselves out and make a weak field.
@@icecube-n2d that is true for changing the winding direction (for example from clockwise to counterclockwise). As long as the direction stays the same it doesn't matter if you move left or right within a layer. Changing the winding direction accidentally is almost impossible because you would just start to unwind the coil
can u explain why it works like that? I wasted so much effort moving the wire back every layer ig
@@icecube-n2d When current flows through a wire it creates a magnetic field around the wire. When the wire is in a coil the magnetic fields combine into a single field. The right hand grip rule can be used to find the direction of the field. The interactions between the magnetic fields in each loop of the coil are pretty complicated but basically the magnetic field forms perpendicular to the direction of the current. If the direction of the current changes to opposite (if the direction of the winding in the coil changes) the magnetic field also flips and cancel itself. Any part of the wire that goes horizontally across the coil creates a magnetic field 90° from the main field and it doesn't add or cancel the main field.
If every other layer is wound "backwards" the direction of the current around the coil is still the same so the direction of the magnetic field is also the same
Imagine making a gravity gun out of this

Bro created a canon.
Hey man, you do a good stuff, can you do something to prevent neutral leaking to ground on cheap LED Power supply? BTW, Live wire is switched . When LED doesn't touch anything it doesn't glow, glows a bit when touched, and leaking about 2V on tester when screwed to the grounded mounting.

This is how my old fashioned doorbell works 😅
Nice, now i can build my own coilgun
It was 2.999 amps with the short piece of wire too
I almost know nothing about electricity and how it flows, but how are you able to pick up the coil without getting shocked? Probobly a very stupid question but i would like to know.
That's also the same principle that magnetic trains use
You can create lift with that idea and concept you should make it
I am very curious if the number of amps or the voltage influences how strong the magnetic field is. For example, is 12V at 5 amps as strong as 24V at 2.5 amps?
Question: Will it warm up
there will always be résistance no matter what material you use, you can never be 100% efficient
more current = more wasted power = more heat
@@AAHAHHHHH what about superconductors? 😌
@@Abcdefg25152 you spend energy maintaining the cold temp
@@AAHAHHHHH thanks for info
Given the figure of 50V and 3A (=150W), the coil is going to get very warm, very fast.
my man found rail gun
just use photo resistance..make in every part of coil
Isint a electromagnet essentially a short circuit? Or why would the coil get hot?
How do you switch it off at just the right time? I doubt u could do it manually every single time just right 😅
The prison weapons blueprints
yoooo it’s the phantom forces advanced coilgun at the end segment
great game y’all should play it
Why not it short circuit if voltage connected to both ends of the wire? 😢
Loved the video but came here to say "wireeeauuurrrh"
you can make ac current in coil
Would using silver wire for stuff like this make a more effective and powerful electromagnet?
Yes, but it’s cost prohibitive
That’s the coil gun from phantom forces
Helpful
And that's how's the speaker made 🙌
An important part of the electromagnet is the fact that the wire is covered in a plastic coating to cause the current to traverse the entire coil.
What a stunning news! Ladies and gentlemen, standing ovation, please.
@@jarekferenc1149 no need to be snarky. I was just informing people as the video is evidently targeted toward people who don't have a deep understanding of electromagnetism/circuits.
that last picture of the white coilgun is from phantom forces and I know that because I play phantom forced
Electro boom did this
if you add more in series, you get diminishing returns. a gauss gun is a thing, limited by poor power storage.
The wires have to be rubber coated or else it will just heat up
How do you determine the exact righr timing?
This would work even better if you wrap it around a screw or a bar of metal
Magnetic Force (MF)
I saw that pf coilgun
Someone needs to make an effective and cheap coil gun so that the British have to ban copper wire.
A coil gun is already banned by the law 😉
do it in a circle 😂💯
this magnet is 1000x weaker than it could be cause of no core
Instead of timing it just add a switch inside
a neater wound coil would perform better. but take longer
came here to figure out how the gun from DRG (theoretically) works
isnt that the coilgun from phantom forces
i was looking for this comment
*Railgun Acquired*
Could you use this with another coil after and apply lenz law and repeat the process over n over. Would it be worth the electromagnetic energy lost vs the energy gained?
