The N-S field on the magnet goes up and down.The current flows from center to horizontal. A moving current at right angle to magnetic field will develop a right angle force, pushing the wire. As the wire spins it makes a back force in the same magnetic field and limits the speed. If you hang the magnet on a screw, and hold the wire and battery still, the magnet will spin super fast the other direction because the magnetic field is reversed in the magnet and the force that it makes as it spins is supporting the rotation (also backwards like before). A fun alternative is magnets at both ends with N poles facing inwards. Magnets must be bigger than battery. Lay it on aluminum foil and it will roll away. Use different size magnets and it will go in circles.
A homopolar motor creates rotational movement because of what is known as the Lorentz force. What's happening is that electrical current is flowing from the positive terminal of the battery to the negative and into the magnet.
OK, I’m going to get scientific for this bit so make yourself a cuppa and bring your concentration face! A homopolar motor creates rotational movement because of what is known as the Lorentz force. What’s happening is that electrical current is flowing from the positive terminal of the battery to the negative and into the magnet. This current then flows from the centre of the magnet to the edge where the wire connects, it travels up the wire back to the positive terminal of the battery and the circuit is complete. Simple. But how does this generate movement you may well ask? Well, the key is the direction of the current and the magnetic field produced by the permanent magnet. We’ve put together the below diagram to support the explanation. The direction of the magnetic field is demonstrated by the red arrows and the direction of current is shown by the blue arrows. As the current travels perpendicular to the magnetic field, a Lorentz Force is exerted on the on the conductor (the wire) which again is perpendicular to both the direction of the magnetic field and the current, generating the spinning motion.

Let me help Kuroi out. I teach this in my college physics course. The button magnets have a "dipole" magnetic field, it exits the magnets vertically, makes a loop and reenters the magnets at the bottom. At the bottom of the battery where your wires are horizontal the B-field is mostly vertical. Force = Current * Length cross B-field. The cross product of a horizontal wire and a vertical field is a circumferential force. It's very slick!
What’s happening is that electrical current is flowing from the positive terminal of the battery to the negative and into the magnet. This current then flows from the centre of the magnet to the edge where the wire connects, it travels up the wire back to the positive terminal of the battery and the circuit is complete. Simple. But how does this generate movement you may well ask? Well, the key is the direction of the current and the magnetic field produced by the permanent magnet.

As the current travels perpendicular to the magnetic field, a Lorentz Force is exerted on the on the conductor (the wire) which again is perpendicular to both the direction of the magnetic field and the current, generating the spinning motion.
LOL. I know how it works but the description of how it works that you simply cut and pasted from some other source doesn't help others when there is no diagram to which the description refers. :)
it is true but hideous to understand. since the experiment worked then it could be set as a model. the rotation is caused by the strength of the magnetic fields and the magnetic fields coming from the battery through the wire they both attract and oppose one another making either one of them to rotate. if you are applying electricity then it is called an electric motor, if you have two magnets that holds together and you are applying force to move them apart in a rotational manner then it is called a generator or a dynamo.
It works because of the loretz force, the magnetic field of the magnet is going up, the electricity is going sideways, so you have a perpendicular motion to the magnetic field.
take something like scissors and make a dent using it's tip in the middle of the batteries tip; make sure the bottom part of the wire doesn't squeeze the magnets. Only one of them touching it at a time is enough. And then watch it go crazy!
Like any other electric motor, the homopolar motor is driven by the Lorentz force: as they move through an external magnetic field, the current carriers in the conductor experience a push that is perpendicular to both their velocity and to the external magnetic field. This force induces a torque around the axis of rotation. Because the axis of rotation is parallel to the external magnetic field, no commutation is required for the conductor to keep turning
It's easy since copper in non polar which means magnets don't stick to it and the neodymium magnets conduct electricity you end up creating an ac motor, and it spins because of the magnetic field created by the battery
+Cary Gonzalez So what happens is the copper is non magnetic, so the magnets don't stick to it. And the type of magnet he is using conducts electricity because it's a metal. so when you put the wire on both the battery and the magnet it completes the circuit, but also creates a electro magnet. And it's because of the magnetic fields from the electro magnet that was just made and the magnets you already have attached to the battery it makes the wire spin
A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis that is parallel to the magnetic field.The EMF (electro magnetic flux) it produces is continuous in one direction so it doesn't need a commutator (the moving part of an electric motor) but it still has to rotate .
Let me explain. :) I just learned this in physics. :) A magnet has a field around it called a magnetic field. It works kind of like a gravitational field, where it can affect things in the field. Obviously the further from the field, the weaker the magnetic field is. In physics, I learned that if you place a charge object into the magnetic field, it will move. The battery charges the copper wire on contact. Negative electrons move through the wire. By the wire touching the magnets it's a
A homopolar motor is an electric motor that works without the need for a commutator, by rotating along a fixed axis that is parallel to the external magnetic field produced by a permanent magnet. The name homopolar indicates that the electrical polarity of the motor does not change Such motors necessarily have a single-turn coil, which restricts their practical applications, since they must be used with low voltages and produce relatively small torques.
This is because when electricity flows from Cu(copper) it produces a magnetic field as the magnets are connected to the -ve terminal. It causes attraction and repeltion.
Did anyone answer you yet how it works? Current passing through the circuit has a rotating field around the wire. Because of how you bent the wire, the force of the magnetic field around the wire points in opposite directions at either end of your rotor so it spins. The same principle works for larger electric motors, they just have a lot more wire in the coils and consume more energy so they can produce greater torque and power. Hope that helps.
iqbal mahmud To be more clear I'd need to draw pictures. A more detailed explanation has more technical language that is more confusing without pictures or setting up a lab experiment video. For better explanation look up videos about "how electric motors work" "electromagnets" "electricity and magnetism". I'm sorry my explanation wasn't helpful.
+Nick M Just use flemmings left hand rule that will explain this perfectly.. I was just as boggled as everyone else here when i saw this experiment 4 years ago... now i get it :)
Aakash Joshua I left that out of my text description because that would make it more complicated without being able to draw it. The left hand rule will surely be in the explanations of the search terms I mentioned.
***** i made something like this with a tiny motor and 2 paper clips... my science teacher loved it and it buzzed and it almost flew off and she said it felt like something for your hands or feet at the spa
It works because of the Lorentz force. The Lorentz Force formula is: F=i L x B L is the lenght of the wire, i is the current and B the magnetic field. x is the vectorial product. It means that, if you have a magnetic field and a current that are not in parallel, you can create a force and find it's direction using the right hand rule. As you have 2 wires, you get 2 forces. So, your torque will be doubled. If you get a better battery and increase the current, you get a higher force->torque
Assuming the magnets conducts current from the positive pole to the negative one via the copper wire. So there's Two magnetic fields. One from the magnets and one around the wire (because of the current) The combinaison of these two fields creates a force perpendiculary to the wire and horisontally. so we have a couple of forces that makes the wire turn around the battery. Normally if you inverse the magnets it turns on the other way. Please excuse me for non-perfect english , i'm French
I did this a few years back, its easier to make a spiral around the battery with just enough clearance so it doesnt get off the top terminal. With less mass, less energy is taken to spin it so it spins faster and more efficient
I think the permanent magnet doesnt amplify the Lorentz Force but rather gives it a counterpart where it can "grab" on. Not sure though. You could try this by not putting the magnets in direct contact with the current circuit.
The coating on the magnets are conductive so there is current in the copper wire. the negative side of the battery is on bottom so electrons are moving from bottom to top in the wire. This current is symmetric about the wire's symmetry. From there, the magnets have a dipole field which pretty much runs parallel along the axis of the battery at the general area where the wire is touching the magnets. The magnetic field also extends up to the top portion of the wire but it is weaker there so we can neglect that. With the magnetic field and the current in the directions as they are, it creates a force on the wire in the circular direction with the equation (F = qv X B), where F, v, and B are vectors.
+Jeff Rainwater Thanks for the reply. I'm not really trolling or anything..lol. I've just taken a class on electricity and magnetism since i'm an undergraduate in physics and I just posted what I thought was the right way to explain how this thing works.
looks like it works sort of like a speaker almost. electric current excites the electrons in the copper, these electrons interact with the magnetic field then "ride" the magnetic field and the copper does work.
The magnetic field reacts on the negative side of the battery in the connection of the copper wire where Magnetic force plus chemical force plus mineral force so all the three items plays their parts in the result of less mass item spin thats the copper wire.
i love how you upload so many videos that are consecutively amazing, your not like some others that just have like one or two good videos every single one of yours is brilliant. keep up the great work!!!!
charged object in the magnetic field. There for the wire spins. On a side note: This is how you can find the direction the magnetic field flows. It's a little complicated to understand if you didn't take a physics class, but I'm sure some where out there, there is a easier was to explain this....At least on a level where physics can be explained for everyone who hasn't taken the class. Lol. :)
... if you split the two ends of the two wires that attach to the bottom magnets - it will not spin ! ... the spin is caused by that connection ... if you reverse the current bottom connections to be on the other side - it should spin the other way ... although this can depend on the make-up of the magnets at the bottom of the battery ... thus how it works is the electromagnetic field is pulling or pushing - depending on which way round the battery is ... against the magnets at the bottom ... that offset angle is all it needs ... the bottom half of that wire ... because of the angle of the wire against the magnets is how that effect is done ... hope this helps mate :-) ....
Gareth Wood Hi Gareth, my son tried to make this little motor but it just does not want to spin , we have watched so many of these videos in oder to see if we are doing something wrong but it still will not spin. could you please help us out.
mendez31971 ... needs an electric field caused by the charge from the battery ... you also need strong magnets ... the final thing to do is note the ends of the copper wire - furtherest from the battery ... they are not completely vertical like the battery is - slight angle ... and the other side is the same ... try pausing the video at the right time and you will see both the two ends of the copper wire are at the same angle ... this causes the electromagnetic field on the copper wire to push at an angle instead of directly down or up against the magnetic field caused by the neodymium magnets at the bottom of the battery - it will then spin ! ... the solid magnets must be strong type like Neodymium Magnets ... those type of magnets can increase the effect of the electromagnetic field also ... hope this helps :-) ....
So what is happening here is that you've bent a piece of copper wire into a pattern. So far so good. You've attached neo mags to a di-pole battery also good. You put the two together and science happens and by that I mean I have no clue how this works but it's awesome.
The wire spins in the direction that it does because of Fleming's left hand rule. If you hold your lefy hand pointer finger pointing in the direction of the magnetic field, and the middle finger at 90 degrees to that in the direction of current flow, the thumb will point in the direction that the wire will spin. Remember that current flows in opposite directions in the two wire paths, so they push in the same counter clockwise direction as shown in the video.
it is basically a circuit. the electric current travels down through the battery up through the copper and back down again while the magnetic field is going in the opposite direction. what causes the motion though is how the wire is perpendicular with the current of the battery. that perpendicular angle disrupts the movement of the current and causes the motion of the copper wire
The wire gets pulled at all sides because of the electromagnet, which causes the wire to spin. On big motors theres a bobbin used to spread electricity to metal which creates electromagnet. Then in the middle of the metal theres a steel cylinder with wire wrapped around it. When you turn on the motor the wires get pulled at all sides to cause it to spin. This is how it most likely works. I think. Or know
A homopolar motor creates rotational movement because of what is known as the Lorentz force. Whats happening is that electrical current is flowing from the positive terminal of the battery to negative and into the magnet
When electricity runs through a wire, it will create a magnetic field and a force called the Lorentz Force. This is quite weak usually, the magnetic field of the permanent magnet(s) strengthens it. At least that's what I made up from the wikipedia article.
I think it is because the copper wire gets a magnetic field when current from the battery runs through it. It has a north and a south pole. It is repelled by the pole of the neodymium magnets and then the copper wire rotates.
cu-wire touching both positive and negative ends of the cell,means current flowing on the wire.then conductor carrying current in magnetic then experinces a force on the conductor..thereby producing the torque due to which the rectangular wire rotates...
This works on the same principle the Motors work[Magnetic effect of electric current]. Passing electric current through the copper makes it act like an electromagnet which is constantly attracted and repelled by the magnets turning the entire system into a motor.!!!
It works because there is a current carrying conductor in a magnetic field with relative motion between the 2. This is called motor action and is required for all electric motors.
It's called EMF, electro-motive force. When there is current and a magnetic field, movement is generated. Just like when there is movement through a magnetic field current is generated.
the copper wire has got current flowing through it making a small magnetic field. the magnets also have a magnetic field these fields oppose each other enough to make it spin, then the magnetic fields line up and oppose each other again. if you have more copper wire and get the magnetic fields to oppose more wires it will spin faster. hope i helped
Also, there is no electromagnetic induction here since the dipole field is symmetric with respect to the same axis as the wire's symmetry.....i.e. there is no rate of change of magnetic flux
electricity travels through magnet and radiates outward from the center. this causes a magnetic field to form and continually change causing the wire to move
it works because of the magnates because of the two bars beside the magnates they are both pulling in the wire the magnates are stacked so it is going up and down the bit on the top is spinning and picking up momentum so that it is spinning
The N-S field on the magnet goes up and down.The current flows from center to horizontal. A moving current at right angle to magnetic field will develop a right angle force, pushing the wire. As the wire spins it makes a back force in the same magnetic field and limits the speed. If you hang the magnet on a screw, and hold the wire and battery still, the magnet will spin super fast the other direction because the magnetic field is reversed in the magnet and the force that it makes as it spins is supporting the rotation (also backwards like before). A fun alternative is magnets at both ends with N poles facing inwards. Magnets must be bigger than battery. Lay it on aluminum foil and it will roll away. Use different size magnets and it will go in circles.

Not 4, but 4 thousand
It works because of the Lorentz force.
The Lorentz Force formula is:
F=i L x B
L is the lenght of the wire, i is the current and B the magnetic field. x is the vectorial product. It means that, if you have a magnetic field and a current that are not in parallel, you can create a force and find it's direction using the right hand rule.
As you have 2 wires, you get 2 forces. So, your torque will be doubled. If you get a better battery and increase the current, you get a higher force->torque
Fun fact if the battery is turned upsidown it spins the other way
fun fact, we all know!
Assuming the magnets conducts current from the positive pole to the negative one via the copper wire.
So there's Two magnetic fields. One from the magnets and one around the wire (because of the current)
The combinaison of these two fields creates a force perpendiculary to the wire and horisontally.
so we have a couple of forces that makes the wire turn around the battery.
Normally if you inverse the magnets it turns on the other way.

The captions are ridiculous but funny.
This guy definitely needs more views. One of the best channels on RUclips for sure!
this defied all my scientific study
how so?
How?
Pretty amazing!
Yeah, the same question. How?
pretty simple.. read Fleming right hand rule
Magnics produce energy, with the battery giving it power causes the copper wire to rotate sort of the same sense as the earth rotating
Is this how Sony was hacked?
Its the positive and negative charges makes part of it run but the battaries takes all that power into making it spin
what he said
Open the captions you all will laugh
0:29 bit is the best LOL
One of the captions word had a percentage sign in it. XD

From Andre,The battery gives elitrisity trough the wire and it gowes round and round . your a good scintist
it works by magic
No it dos'nt. it works from a charged magnetic force pulling and attracting the ends of each wire
I did this a few years back, its easier to make a spiral around the battery with just enough clearance so it doesnt get off the top terminal. With less mass, less energy is taken to spin it so it spins faster and more efficient
don't work.why

Possibilities:
-Dead battery
-Weak magnets
-Insulated wire not making contact with battery terminals
...Could be a few other things.
Nicely done! It's the magnetic field interacting with the wires that causes this force. Electromagnetism.
I have Numa Numa dance.
***** Watch the video with captions on.
HUS MAN heha his brother is pretty :D
Hayatabad they gonna drop all couple
The pixies are angered. Then rotation occures! Cheerios:-)
where we will find that magnet
Home Depot has them.
in market
They are labeled: "Neodymium" magnets. They are the very strong magnets.
+bluegreen1548 search in eBay or some online websites even I want them.
+Akif Khan You can take them out of dead hard drives.
But seriously u make some very useful video's great job man keep going! Also you should make some more zombie survival tactic videos!
I think the permanent magnet doesnt amplify the Lorentz Force but rather gives it a counterpart where it can "grab" on. Not sure though. You could try this by not putting the magnets in direct contact with the current circuit.
The coating on the magnets are conductive so there is current in the copper wire. the negative side of the battery is on bottom so electrons are moving from bottom to top in the wire. This current is symmetric about the wire's symmetry. From there, the magnets have a dipole field which pretty much runs parallel along the axis of the battery at the general area where the wire is touching the magnets. The magnetic field also extends up to the top portion of the wire but it is weaker there so we can neglect that. With the magnetic field and the current in the directions as they are, it creates a force on the wire in the circular direction with the equation (F = qv X B), where F, v, and B are vectors.
+Mike P I'm honestly not sure if this is a pro troll or if you are seriously brilliantly smart.
+Jeff Rainwater Thanks for the reply. I'm not really trolling or anything..lol. I've just taken a class on electricity and magnetism since i'm an undergraduate in physics and I just posted what I thought was the right way to explain how this thing works.
Yet another awesome video! I already know how these work, but I like your design, and I love how simple these motors are.
looks like it works sort of like a speaker almost. electric current excites the electrons in the copper, these electrons interact with the magnetic field then "ride" the magnetic field and the copper does work.
Don't know which is better, science or accent. You are awesome comrade!!
The magnetic field reacts on the negative side of the battery in the connection of the copper wire where Magnetic force plus chemical force plus mineral force so all the three items plays their parts in the result of less mass item spin thats the copper wire.
good job. I liked it, and I hope you make a video with more electrical experiments.
i love how you upload so many videos that are consecutively amazing, your not like some others that just have like one or two good videos every single one of yours is brilliant. keep up the great work!!!!
charged object in the magnetic field. There for the wire spins. On a side note: This is how you can find the direction the magnetic field flows. It's a little complicated to understand if you didn't take a physics class, but I'm sure some where out there, there is a easier was to explain this....At least on a level where physics can be explained for everyone who hasn't taken the class. Lol. :)
... if you split the two ends of the two wires that attach to the bottom magnets - it will not spin ! ... the spin is caused by that connection ... if you reverse the current bottom connections to be on the other side - it should spin the other way ... although this can depend on the make-up of the magnets at the bottom of the battery ... thus how it works is the electromagnetic field is pulling or pushing - depending on which way round the battery is ... against the magnets at the bottom ... that offset angle is all it needs ... the bottom half of that wire ... because of the angle of the wire against the magnets is how that effect is done ... hope this helps mate :-) ....
Gareth Wood Hi Gareth, my son tried to make this little motor but it just does not want to spin , we have watched so many of these videos in oder to see if we are doing something wrong but it still will not spin. could you please help us out.
mendez31971 ... needs an electric field caused by the charge from the battery ... you also need strong magnets ... the final thing to do is note the ends of the copper wire - furtherest from the battery ... they are not completely vertical like the battery is - slight angle ... and the other side is the same ... try pausing the video at the right time and you will see both the two ends of the copper wire are at the same angle ... this causes the electromagnetic field on the copper wire to push at an angle instead of directly down or up against the magnetic field caused by the neodymium magnets at the bottom of the battery - it will then spin ! ... the solid magnets must be strong type like Neodymium Magnets ... those type of magnets can increase the effect of the electromagnetic field also ... hope this helps :-) ....
Gareth Wood Wow it works, thank you very much for your help and for taking the time to help my son , it has put a big smile on my sons face
... glad to help :-) ....
So what is happening here is that you've bent a piece of copper wire into a pattern. So far so good. You've attached neo mags to a di-pole battery also good. You put the two together and science happens and by that I mean I have no clue how this works but it's awesome.
I love your videos, they're not too long so they hold my attention span, but they're still interesting. Good job!
The wire spins in the direction that it does because of Fleming's left hand rule. If you hold your lefy hand pointer finger pointing in the direction of the magnetic field, and the middle finger at 90 degrees to that in the direction of current flow, the thumb will point in the direction that the wire will spin. Remember that current flows in opposite directions in the two wire paths, so they push in the same counter clockwise direction as shown in the video.
it is basically a circuit. the electric current travels down through the battery up through the copper and back down again while the magnetic field is going in the opposite direction. what causes the motion though is how the wire is perpendicular with the current of the battery. that perpendicular angle disrupts the movement of the current and causes the motion of the copper wire
Wow i really like how many videos hes putting out now. Both quantity and quality. Awesome stuff keep up the good work
The wire gets pulled at all sides because of the electromagnet, which causes the wire to spin. On big motors theres a bobbin used to spread electricity to metal which creates electromagnet. Then in the middle of the metal theres a steel cylinder with wire wrapped around it. When you turn on the motor the wires get pulled at all sides to cause it to spin. This is how it most likely works. I think. Or know
Safety is the number one pworitye... Hahaha... dude you are amazing
I've been trying to do this for the past few weeks and it doesn't work for me!
Does anyone know why?
The copper release energy from the battery so it moved. the more energy it release the more faster it spin so try enegizer just a suggestion
Nice video, i would like to inow how to do the compression air explote, Im from Mexico, I love ur videos
Is there a use for this kind of motor you make with battery and magnet? Your videos are the best! peace out!
you sir have inspired me to try and make something thank you
Love watching the stuff that you do. A great entertainer to RUclips!
I'm new to your channel and i just have to this, your voice sounds so majestically like Arnold Schwarzenegger
The magnetic feild acts on the particles in the current causing the particles to force the copper wire to start spining
yep the what's it mafeld acticed on it so yeah it spun
Homopolar motor
A homopolar motor creates rotational movement because of what is known as the Lorentz force. Whats happening is that electrical current is flowing from the positive terminal of the battery to negative and into the magnet
could you add a little tape stacked on top of each other on the edges of the battery to create a wall and keep it going for a lot longer?
When electricity runs through a wire, it will create a magnetic field and a force called the Lorentz Force.
This is quite weak usually, the magnetic field of the permanent magnet(s) strengthens it.
At least that's what I made up from the wikipedia article.
Hmm... some improvements to the design. It could be a cooling fan. Sails on the sides. Need to improve it's stability so it wont fall off.
Nice
It works on the principle of elctro motive force........
Electricity plus the magnetic field produces movement. thats the basic principal of any electric motor.
I think it is because the copper wire gets a magnetic field when current from the battery runs through it. It has a north and a south pole. It is repelled by the pole of the neodymium magnets and then the copper wire rotates.
cu-wire touching both positive and negative ends of the cell,means current flowing on the wire.then conductor carrying current in magnetic then experinces a force on the conductor..thereby producing the torque due to which the rectangular wire rotates...
I agree. Or Jeorg Sprave. He and RussianHacker are just so gifted and imaginative.
This works on the same principle the Motors work[Magnetic effect of electric current]. Passing electric current through the copper makes it act like an electromagnet which is constantly attracted and repelled by the magnets turning the entire system into a motor.!!!
wow that was awesome how does that spin on a dead battery like that?
Verry good! Prof.Dr. Dr. B. Suthoff, Germany
i love when you said "Awesome"...
It works because there is a current carrying conductor in a magnetic field with relative motion between the 2. This is called motor action and is required for all electric motors.
You can stick papers on both the sides of the rectangular frame and it will work like a fan.....;)
Very cool experiment
that is so cool, just need to figure out a way to use it in a zombie apocalypse!!
is there any torque that is equal between the two moving parts?
For those of you who are wondering what he says in the beginning, he says "Welcome to my laboratory"
It's called EMF, electro-motive force. When there is current and a magnetic field, movement is generated. Just like when there is movement through a magnetic field current is generated.
Electro-magnetic Field, not electro-motive force, but both stand for EMF.
Fun fact: Did you know a mini black hole can absorb your thoughts and show you visions of a universe stored inside?
It works when the magnet extracts energy from the battery faster than the other side so it goes more to the other side and it spins
the copper wire has got current flowing through it making a small magnetic field. the magnets also have a magnetic field these fields oppose each other enough to make it spin, then the magnetic fields line up and oppose each other again. if you have more copper wire and get the magnetic fields to oppose more wires it will spin faster.
hope i helped
Also, there is no electromagnetic induction here since the dipole field is symmetric with respect to the same axis as the wire's symmetry.....i.e. there is no rate of change of magnetic flux
It works because of the electro magnetic plus in the battery and coperwire that thus produces a motor that created motion of the wire
What size are those neodynium magnets
Cool! Now my car has a new motor!
LOLLL XD
this made my day :D XD XD
electricity travels through magnet and radiates outward from the center. this causes a magnetic field to form and continually change causing the wire to move
watch out , we've got a scientist over here :)
The motor works because the copper wire reacts to the magnetic field that the magnets and the battery produce together.
Friend could you tell me where do you get the magnets from? thank you, I love your experiments, and the fun, just can miss it...
lol. When your chainsaw motor breaks, you will use this.
it works because of the magnates because of the two bars beside the magnates they are both pulling in the wire the magnates are stacked so it is going up and down the bit on the top is spinning and picking up momentum so that it is spinning
