- #Roobert33 Shares in a magnetic field of a magnet. The wheel of Barlow is a tool purely didactic, but is an example of an electric motor, in fact it transforms electrical energy into mechanical energy. The metal wheel with a horizontal axis has the edge outcropping in the mercury contained in a tank. An intense magnetic field is generated by a magnet. To the two clamps set on wooden board it connects a battery or a power supply of 12 volts DC. The circuit goes from the clamp at the center of the loop down along the wheel and get into the tank where is located the mercury below which there is a wire connected to the other clamp. As soon as you close the circuit the wheel starts spinning.The explanation lies in the Lorentz force acting on the electrons which run radially when it closes the circuit. / @electricexperimentsro...
What is with all these girls crying about the mercury? How do they even find this video? It is an excellent demonstration.
Nice mercury mist maker.
Nice build. It has the look of the original 1890 version. Love the wood stain and brass (and copper). The mercury... not so much.
Brilliant video. Your set up is done to absolute perfection as usual.
The copper disk if it is made to rotate manually without the aid of the battery becomes a dynamo and generates electric current.
When turning it absorbs various amps, the voltage drops only a few volts :)
Больше опытов с без вредной ртутью💪 ртутные антенны, ртутные двигатели, ртутные лампы освещения, ртутные колеса, ☝️
Thats some more absolutely bazaar stuff,....love it!
Mercury tastes pretty good. I take a shot of it every now and then.
+Rodney Massie and you're still alive?
+Diego Enriquez I would never eat mercury. I think that disk making the mercury fly out and become air born is dangerous.
Гениально. До этого некто не додумался постоянный магнит использовать для получения электричества.
Excellent take on the Faraday motor.
Physics is incredible 👏🏻
You deserve more than 8000 subscribers, but I suggest that you explain to us in ur videos the concepts and the instructions.
This is what Ed Leedskalnin had at Coral Castle. The concrete wheel with the 24 model t u-magnets filled with mercury with the chain dropped in and the mass of iron for the voltage drop(light bulb).
We did this at school, using a pool of mercury. Every time the spike touched the mercury there was a little flash and puff of mercury vapour emitted. Probably took 20 points of IQ off everyone in class. Except me - I held my breath and backed away.
Este es un motor homopolar de Faraday...Pero tiene un problema grave: EL MERCURIO ES TÓXICO!!!...Debieras probar y reemplazarlo por una solución de agua acidulada o salada...Por ejemplo H2O + HCl...O puedes probar con H2O + NaCl también...Pero es un buen experimento...Saludos.
La vida es tóxica, al final te mata.
انها اكذوبة كبيرة لان المصباح يجب ان يومض بسبب تناوب شفرات العجلة
لكنه في التجرة يضيئ بشكل مستمر وهذا يؤكد انه يوجد خدعة كبيرة 👌👌👌👌
لا تنسي انو في سرعة دوران كبيرة وبآخر الفيديو لما صار يوقف الدولاب صار يومض المصباح لان السرعة انخفضت
Brilliant ,Thx Roobert.
I hope you can build a Kapagen experiment too!! great video
Oh dear, mercury everywhere. I feel like I am going to get poisoned just looking at it.
I have not poisoned myself, do not worry.
are you sure? aerosol mercury is hard to avoid
@@ElectricExperimentsRobert33 Ha, ha, how do you know, after intoxication?
What is in the small beaker?
Liquid mercury
I think that the mercury can be replaced with water and salt solution, and without the current limiting light bulb. Still not sure that a sufficient current will flow through the water, but you can give it a try. Maybe on 24 or 48 volts.
The saline solution is not sufficient to move the motor ;)
Could you replace the mercury with saltwater and get the same results? very cool thanks for sharing.
+Jerry Rauch The salt water in this experiment does not give optimal results such as mercury.
Ok, thank you
You can use acidified Copper sulphate solution.
+Miles Pereira
It is good for small powers, but being an aqueous liquid does not have a power as high as the mercury which is a liquid metal for maximum electrical conductivity.
+Roobert33 It would just add resistance to the circuit ... just like your light bulb.
will it be more efficient if the disk is round plate and i use brush instead of mercury ?
the copper disk needs to be done in segments, otherwise if it's flat disk is not working. The brush is also good to run it.
Series bulb is connected to the circuit inorder to avoid short circuit is it
Nice vedio
Thanks for sharing
Very nice :-)
Sir, that is beautiful, but the light bulb looks like 240 volt, 60 watt, running on that 12v battery - please advise - kind regards - Ben
What is utility of mercury in this experiment?
Because it's good conducter of current but main reason it's conducter with low resist with wheel so that wheel can move frictionlessly
Jakhon wheel ta start holo darun lagchilo
de que voltaje e sel bombillo. que voltaje provee este ??
Please write the characteristics of the accumulator battery and incandescent lamp (current, voltage and resistance). 🙏 when I add a lamp to the circuit, it glows, but the barlow wheels do not rotate. without a lamp it rotates at high speed.
really cool
This is just another form of Impulse Driven DC Motor - - they've been around before Faraday!
There is no commutation going on!
Yes this and another beam type was adapted from a steam engine by Bourbouze: both were early DC motors. Or Davenport's in the US that uses brushes and commutors. But they were not practical economically. Only with the development of AC motors and dynamos did it become a serious source of motive energy.
why you are puting your finger in mercury its not dangerous ?
+Alex Dinca and when you inhale it, too
Complimenti molto bello
when this motor drives an axle and fan blades the blades stop splashing out the mercury from the bottom of motor by making flow of air when not light bulb in the circuit
not too popular with the mercury i guess
This is awesome
Dose it even need the battery can it just be run linked ?
OMG! That's awesome!
with water work but you need water+salt
the system only works with mercury, with salt water I tried but did not give a good rotation.
Have you tried Arm and Hammer washing soda. Salt water gives off chlorine gas.
I found a used Barlow wheel that uses mercury. New don't use mercury anymore. What size battery should I use? A 12v made sparks and threw mercury all over. A 9v does not do the job. I hope to hear from someone.
Of course 12V is too powerful, 9V you say it is little, actually 9V is ideal. If it doesn't work at 9V, there is some hitch in the system. You have to check it well.
it is also a generator. use brine
wow look at the miniscule 12 volt dc battery lighting an incandescent lamp rated for much higher voltage!!!
Hi.Thank you for the video.I have a round 10 cm diameter brass disk,4 hdd magnets and a coal from a drill.will i be able to replicate faraday disk ?
Возьми стальную ось с двух сторон подключи к аккумулятору через ртуть, будет вращаться в разы быстрее и ртуть не улетит...
So with a load greater than itself in series the wheel acts as an A/C oscillator, and when the wheel is the load it acts as a simple D/C rotor? Please forgive me if my question sounds silly.
+Paul Trace No, it's always just a simple D/C rotor. The reason it spins faster without the lightbulb in series is because the motor is basically a short between the battery poles, letting many amperes run through the rotor.
Do you think it works with copper wire instead of mercury? What current and how many Ampere do you need to spin the wheel?
With the copper wire does not work well, absorbs too many amperes..
Nice experement
will iti work if it`s made of brass ?
I have not tried it with a sheet of brass, but I think the brass does not have electrical properties such as copper. You have to give it a try if you are not working too :)
What does it mean it absorbs to much amperes. If i measure the flowing current i get first about 10 A (with two 9V batteries parallel) but then the amperes drop to 0,4 A. Where did the Amperes go and why doesn't this happen with mercury?
The mercurybeing an liquid metal, absorb less current compared to a solid metal. The mercury has a molecular feature.
I also want to replicate Barlow’s experiment. I was wondering if one could make the wheel turn on a simple galvanic cell/Daniell cell (1,1V, 500μA) or, for example, your salt water experiment.
It works poorly with the salt water, is not suitable for this type of experiment..
Т.е это печатный ротор с жидким коллектором? Можно примерные параметры момента и тепловыделения?
If you could make a very low friction commutator type of wiper (like phosphor bronze wire) to the wheel, you would not need the mercury to do the job, would you?
Yes, it is possible..
A tasty brine works well too. Also, I believe the "vanes" are superfluous. The copper disc shown near the beginning of the video (before cutting away the vane voids) should work.
"Electric Experiments"Roobert33
o..0 Don't touch the mercury with bare hands! . . . I'm sure the vapors are causing you brain damage too. . . pencil graphite would be much better, but it is a cool motor.
Todd Stafney It wouldn't rotate then
MrGimli2 It would still rotate. Have witnessed. Wikipedia confirms: "The presence of serrations on the wheel is unnecessary and the apparatus will work with a round metal disk, usually made of copper."
What is the liquid ?
Liquid mercury.
Mercury

batushka777 The bulb is 12 volts 21 watts, it can also be done with a light bulb 15 watts 230, but not more than 15 watts.
se puede utilizar otro elemento diferente al mercurio? por ejemplo legia
El mercurio para este tipo de experimento es el más adecuado, pero también otros metales líquidos son buenas. no de agua salada.
Esse sim é com água e sal.
can ear something that sound like a light switch 2:09
i do belive that this works but that sound is just odd
Fernando Melo the electrical contact of the copper with mercury is similar to a mechanical contact
ok, thansk
in 3:54 there is not sound o.O
+Peter Dorner No, no sound at that speed, but if you open your ears, to the minute 3:42 you hear the noise of it.
ist das queksilber???
Do you know a non toxic version of this really impressing Barlow wheel? I am an 14 year old student and i want to show it in our physics class in this version which is close to the historic one but my teacher wouldn’t allow me to use toxic mercury. So what can i do?
You can not do anything, the system only works with mercury.
how about Galium ?
wather whit salt? too much salt and more voltage
Brushes - a soft brass brush that touches two of the fingers should work. Then you notice the brushes would work better if what they contact is smoother, and then if it's self lubricating, and the whole thing evolves into a modern dc motor with an armature and carbon brushes.
e.g. ua-cam.com/video/hSfxATaYeSY/v-deo.html or ua-cam.com/video/-T9uCv5imZs/v-deo.html don't use mercury
niceeeeeee👍👍👍👍👍👍👍👌
real cool :D
Fingering Mercury? Not wise....on a prolonged basis.
what is this ,how it work
If you read the video description everything is written..
It is safer if I use a solution of water and salt; you are touching the mercury too, it can be absorbed by the skin!!!
+Fermin Enrique Zamora Pineda Water and salt does not work in this experiment.
+Roobert33 If you were to run it in a vacuum, couldn´t you use NaK instead?
extrem leichtsinnig!!!
😱 Mercury! 💀

no not in water salt
waterconnects metal = electricity flow ? simple
Maklarus Trinity In this video, the water is not as powerful as mercury.
+Maklarus Trinity ~~~Mercury is way better conductor than water,
salt water better conductor than fresh water
bel videooooooo
Mercury or galium
mercury
Bro it is mercury not slim so please dont touch it with naked hand
try it with water?
I've already tried it with water, it does not work ;)
и че в этом такого? ртуть это металл который не плохо проводит электричество... есть и ртутные переключатели
дело в парах ртути
Pave Diesel
начинает испаряться ртуть в районе +70 градусов и лишь тогда она опасна и то ей напаришься дышать, что бы навредить себе...
Макс Мутный
Ядовиты только пары и растворимые соединения ртути. При температуре 18°С начинается интенсивное испарение ртути в атмосферу, вдыхание такого воздуха способствует её накоплению в организме, откуда она уже не выводится (как и другие тяжелые металлы
