Magnetic Accelerator

[@glaucopimenta]

Nice Science sharing project, man! I reproduced the experiment with my students at the high school science fair. Everyone enjoyed it a lot. The students did make it with the same cooper wire (30 AWG), coil turns, resistor, transistor, inductive sensor, steel ball. However, I used a plastic rail more little extensive than yours. The steel ball was not pushed enough by the magnetic field flow. The solution was to replace the steel ball with another magnetic ball of the same diameter (19mm). Thus, the magnetic ball obtained greater magnetic interaction with the coil and received much more impulsive force to circulante along the rail.

[@ludicscience]

Great that you like it! I had no magnet ball around so used normal steel ball

[@PrabishKumarMahato]

What is that circular path?

[@cinescopefilms]

if the rail and ball were placed in a vacuum the speed will be incredible

[@venkateshchintu5510]

Then it's called hyper loop ..lol😊😂

[@suryayenamandra7708]

Slightly faster but probably not much as you'd only be removing air resistance and would still be fighting friction and gravity. Cool idea though :-)

It sounds like the pulse angle is creating back-spin and slowing it down.

Put two more coils with supercaps and diodes then hook it up to a 3 phase supply.

[@anthonydonnelly4069]

Useful for all sorts of things. Simple to implement for a rank amature like me. Thanks

[@timothypb]

It's solenoid action that pulls the ball in, then the inertia carries it around.

[@dominikworkshop6007]

U need a diode connected to the coil to prevent the transistor from damaging due to overvoltages created by the coil

[@anthonydonnelly4069]

I've seen where a capacitor is placed across the transistor in addition to your comment because of the voltage drop delay accessing the diode.

[@raykent3211]

Yes, that's good practice.

[@dheujsnrhfydhehehshshhdggsd]

While that's best practice the simplicity makes it more intelectually accessible.

2:02 proximity sensor applies current to the transistor, turning it on and off. No link given. Might be a magnet attracted to bearing closing a switch. Also a coil on electromagnet could open a gate turning itself off creating a self oscillating circuit. And that oscillating electromagnetic coil inducing into pickup coils becomes generative. Pickup coils can then recharge the source battery.

[@among-us-99999]

The 2N3055 is very robust, such a tiny coil shouldn’t be able to damage it

[@petersmith809]

How about using multiple coils (with multiple sensors) to increase the time of force application. That will reduce the loss of kinetic energy which will raise the velocity.

[@raykent3211]

One nit to pick. To said that the coil pushes the ball. If the ball is ferromagnetic, which I'm sure it is, the coil cannot do that, it can only pull it. So the timing is different,

[@ibmlenovo1]

Could you please explain why isn't the ball attracted.

[@raykent3211]

@@ibmlenovo1 the ball is attracted. Was that a typo? If you're asking for an explanation of why a ferro magnetic material is attracted to higher densities of magnetic field strength, and never repelled, then the answer is very hard theoretically, but easily observed.

[@paulo.tarcisio]

good idea for a school science fair

[@among-us-99999]

Could you supply the coil with a given frequency to precisely control the speed of the ball?

[@ludicscience]

You Will need a precise fequency and coil power

[@1027sterling]

Make the ring a glass tube under vacuum, use a dozen powerful magnet coils- and accelerate the bearing past the speed of sound. Please.

[@strangejmaster]

Uhhh, mate you know how hard that is... This is a simple proximity sensor with no code I believe. Trying to do that might need what you said plus like 30 fans, an Arduino Mega, a few LEDs, and maybe a potentiometer. If that's even possible...

[@davidstonier-gibson5852]

Ahem, define the speed of sound in a vacuum. ;-)

[@mikegLXIVMM]

Good work. Glad to see that the coil does not interfere with the inductive proximity sensor.

[@hyqhyp]

Cool! Use this to make a reverse rolling ball sculpture. Also, I'd like to see this with multiple balls. Maybe as many as can fill the entire ring.

[@charlesmartin1972]

Or, like he said, it could be an inductive sensor. Say you have a resonant LC circuit with a mid-range q factor and you drive it with a signal that has a slightly lower frequency. The LC circuit acts as a bandpass filter on the signal, and as the metal bearing passes by the inductor, it's effective self-inductance increases, increasing the gain

[@charlesmartin1972]

@@daviddavids2884 this is simply how metal detectors work Any practical passive filter has a gain between 0 and 1. When there's a frequency mismatch between the driving signal and the filter, more of the driving signal gets attenuated. By measuring the amplitude of the filtered signal, one can make a circuit that distinguishes between conductive and nonconductive materials You're assuming I'm claiming overunity because you've misunderstood what "gain" means in an engineering context.

[@VincentFumoII]

Dumb question here, but why do you need to turn the coil on and off? Why not just leave it on constantly?

[@yuvraj_3211]

Because if it will be on constantly then the ball might stop under a coil and hence it stops moving

[@Dtechnoster]

Magnetic but from electricity

[@haroldkline4898]

So when is it going to accelerate? I think you need to move the proximity sensor a little further from the coil and give the coil a change to engage the steel ball.

[@mohammedal-alaw6249]

what happens if we increase the turns number I mean is there a chance of increasing the speed?

[@euvo_sound]

others yes but on the other im not sure

[@davidstonier-gibson5852]

It's hard to calculate. The strength of the magnetic pulse will be proportional to Current x Turns or Ampere-turns. So if you double the number of turns and you double the resistance which halves the current (Ohm's law) and you are back where you started. But maybe you can also double the voltage (assuming your power supply has the capacity, which is a wholly different discussion). So we double the turns. But that makes the inductance of the coil FOUR times as much. The inductance slows down the rate of rise of the current when it is switched on. This is where it gets complicated. ;-)

[@gustavgnoettgen]

Nice! I suggest to make the sensor position adjustable, I think it's a bit too near to the coil.

[@athaniaabdulrehman9545]

If voltage was increased could this increase ball speed quicker each time? Right now, it looks balanced where it cannot go faster.

[@nattsurfaren]

If you put many balls in it would it turn faster?

[@jamesbrown99991]

The balls will travel at the same speed, but the coil will pulse at a higher rate

[@nattsurfaren]

@@jamesbrown99991 There is friction in the loop and the ball temporary launches with much speed and then looses the speed thanks to friction. If the loop gets smaller then the opportunity to get the push again comes much sooner meaning that the time with friction decreases. With many balls I believe they would push each other to accelerate even more but I'm not really sure.

[@jamesbrown99991]

@@nattsurfaren the balls are given an amount of momentum by the coil. If the balls don't interact with each other, then they'll all be travelling at the spec of the ball in this video. If you add more balls such that they stay colliding, I think you'll find that the balls end up going slower. The collision will impart momentum from the faster ball to the slower ball; the slower ball which will then lose more energy to friction than it would If there were no collision (friction increases with velocity). If you add even more balls, you will get the coil jammed on and no movement of the balls.

[@davidstonier-gibson5852]

I would expect the ball to eventually bunch up and that would spoil the timing - the coil would be on for the whole length of the "train" rather than the required short, sharp pulse.

Why isn't the electromagnet attracting the ball?

[@ludicscience]

It is!

[@EzeePosseTV]

The coil is basically pulling hard on the ball as soon as the sensor detects the ball. Then in a split second just as the ball reaches near the center of the coil, the coil turns off releasing the ball as it's no longer under the sensor when the ball starts to go through the coil. Giving the impression that the ball is being pulled then pushed when in fact it's being pulled and released very fast.

I still don't know whether the coil is pulling or pushing the ball. Not a good teacher. >

[@jamesbrown99991]

As a good student, you are allowed to think for yourself. The coil is activated when the ball is outside the coil, but travelling towards it. If the coil pushed the ball, it would slow it down.

[@raykent3211]

The ball is simply a steel ball, not a permanent magnet. Steel can only be attracted to a magnet, not repelled. So the coil is turned on as the ball approaches and must be turned off before it leaves, halfway through the coil at most. Timing is sensitive in this implementation. I too was a bit disappointed that these fundamentals were not mentioned.
