I have some questions. 1. What is exactly the interaction between the electric current that is flowing through the copper wire and the metal filings? My assumed answer is that the metal filings are being magnetized and so they are drawn to the copper wire, but I am not sure. 2. When a magnet is spun around a copper wire coil, is the wire producing electricity because the electrons from the wire are being stripped? Where exactly is the electrons coming from? The air? Or the copper wire itself? 3. As a magnet is spun inside a copper coil, is the coil then electrified? Then is that how we transfer the electricity to some kind of conductor that will then send that power to our homes? Want to know more about how the generators are functioned. 4. Last question for now, if electricity is simply electrons that are stripped from negatively charged atoms, then what is the nature of electrons? Is their nature just to flow and transfer that energy until it can settle somewhere? One more question, if magnets repel each other if we face the two like poles, could we not use that repulsion force to spin the generators in powerplants instead of using external power sources like coal, steam water and air? If we could use that repulsive energy that comes from a magnet, we could then have it recharge the magnets so that it can be strengthened so that the energy does not decay over time and use the excess energy to power our appliances is my assumption. Ok that is all I got for now.
@b.e.nazarenko5 жыл бұрын
Hi. I think I can answer some of these questions: 1. The current inside the coil generates magnetic field around it (Biot-Savart law) that makes those metal filings move around the coil. Looking deeper we can say that constant current affects the magnetic moments of elementary particles that "creates" the magnetic field around material. I think quantum physics provides better explanation of it. 2. Well, I can't say what's it caused by in material. In physics it's called "Faraday's law of induction", it says that electric current occurs when the magnetic flux changes in time. 3. It depends on the form of the coil and the magnet. Theoretically you can find a magnet that can be rotated inside a coil and won't cause any sufficient electric current. Again, if the magnetic flux through the coil changes in time then it'll "create" electric current inside the coil. 4. Not only electrons, electric current is the rate of flow of electric charge, it can be created by any charge carrier that changes in time. In metal it's electron, in semiconductor it's electron and "hole". The electrons in metal won't simply move as you wish, talking about electric current, the electrons compensate energy difference between two points (electric potential difference). If there are no energy differene then there are no electric current inside. You should create a potential difference between two points and it can't be made without non-electric forces. 5. You can but it's all about energy. If I'm correct then after some time of rotating something the magnet will become weak because of energy loss. You can read more in articles about remanent magnetisation. Correct me if you find a mistake.

@@b.e.nazarenko Wow I just realized something reading your reply I never noticed before. Do you realize that what said there in one juncture is that a magnet is sort of a capacitor that stores magnetic field just as a capacitor stores electric field. I used the word field instead of the word charge. Since charges create fields. Capacitors store energy in the form of voltage keeping opposite charges apart and storing electric field while in the coils with charge excitation, that are not separated create magnetic field in which when the excitation of charges stops, they use the term collapse, magnetic field collapses, becoming very intense and can cause serious danger crossing through whatever that capacitors can match as bad as they are. Magnets being very complex phenomenon store the magnetic field and unlike coils it takes a long time to lose it depending on the material. And it a permanent magnet magnetism field is not formed by means of charge moving but by means of charges aligning with their so called spin in the same direction.
@b.e.nazarenko4 жыл бұрын
Blue Ocean it all sound right except for magnetic field collapse. As I know, demagnetization of ferromagnetic is described by a hysteresis loop and there are no sharp jumps in it. But you are right about everything else. In coils happens the same as in capacitor, except that capacitor accumulates electric charges and coil accumulates magnetic field.
@alchemy14 жыл бұрын
@@b.e.nazarenko To my understanding when you turn off power to any coil that magnetic field that is accumulated there collapses which I would think It means it can't keep its smooth curl loop by the excitation of the charges so it jumps through any gap and that is what makes transformers dangerous and diodes becomes necessary in circuit boards to protect instruments with every connect and disconnect, rerouting the charges. Capacitors are not used for this purpose as they would act as resonators if used that way with its own consequences. But they can not used to created an imbalance in the distribution of magnetic field as with induction motor to get it going and then turned off and is used as various means. It is interesting how everything has a personality even though those personalities and yet personalities change in different settings for a lack of a better way of saying it I guess. Didn't mean to get poetic on you. :-)
@b.e.nazarenko4 жыл бұрын
Blue Ocean it’s okay. :) The field, that is accumulated in the coil, changes smoothly. According to physical laws, magnetic flux (flux linkage if we talk about circuit theory) changes smoothly. When you turn off the current in a circuit with coil, the field inside the coil creates electric current. For better explanation I provided mathematical explanation of this process: Ф=IL (magnetic flux = current * inductance). e=-dФ/dt=-LdI/dt (Faraday’s induction law); I=e/R => I=-L/R dI/dt dI/I=-R/Ldt We talk about coil with already accumulated magnetic field which is going down because we turned off the power in circuit. So the current changes from I0 to I and time from zero to t (here I is the current at time t and I0 is the current at time when we turned off the power in circuit): ln(I) - ln(I0)=-t/(L/R) ln(I/I0)=-t(L/R) Applying exp function here we get: I=I0*exp(-t/(L/R)) Here we see that the current, at the time when we turned off the power (t=0), equals to I0. And with time it is going down smoothly like exp function does. In transformers problems are caused by Foucault’s currents. Problem comes when magnetic field creates volume eddy currents inside the transformer’s magnetic material. Eddy current transforms it’s energy into heat and the transformer’s material starts heating. If you remember how transformer looks like then you might notice that the center material is not solid but consists of laminations parallel plates. This reduces eddy currents to the volume of one plate. Talking about circuits I remember that diode at input is used for power polarity protection.

@Electric and Magnetic Fields I have one question and but one criticism of this wonderful demonstration: Please in future let your viewers know, early on, the basics: the wire's gauge and the current applied, in case they wish to try the demo and variations themselves. My question is, I have a 5 cm diameter microwave turntable motor which uses a copper coil effectively identical to that in your first demonstration as of 2:24. Within that coil is a cylinder of what I'm guessing is a permanent magnet. Within this cylinder is embedded a gear perhaps 1 cm high and 0.3 cm in diameter. This embedded gear in turn operates 5 additional, interconnected gears, stepping down the 110-120v 50-60Hz AC current to about 2.5-3.0 RPM. Strangely enough i have never seen so much as a diagram of this simple motor, and for the life of me I cannot tell how it gets the initial gear to turn clockwise or counterclockwise, as the operator wishes. Cheers, thanks, and best wishes,
@electricandmagneticfields23142 жыл бұрын
Yes I should have mentioned the gauge of the wire. Any gauge that you can wind into a coil should work. When I do the demo in class I just connect a 9 V DC battery to it, but I don't know the current. I am not familiar with the motor you are describing. I have an old microwave that is not working. I will try to find time this summer to tear it apart and see if it has a similar motor and if I can figure out how it works.

@electricandmagneticfields23147 жыл бұрын
There is actually no gap. There is a magnetic field in the space between the iron filings. The gap seen in the filings is a consequence of the finite number of iron filings. The iron filings appear to be on a line because there is an attraction between each iron filing and the one in front, and the one in back, of it like this, If you could zoom in and put a miniature compass between the iron filings, such as between the two lines above, it would rotate and be parallel to the adjacent iron filings.

Hey man I really think I got the answer, and I don't think it has to do with the number of iron filings. I was reading up on it from a few sources, the khan academy has a reasonable answer (I believe)... The answer is in the 4th sentence in the following paragraph, hope it helps and would love feedback from Mr. Melloch or anyone else, thanks. "Field lines can be visualized quite easily in the real world. This is commonly done with iron filings dropped on a surface near something magnetic. Each filing behaves like a tiny magnet with a north and south pole. The filings naturally separate from each other because similar poles repel each other. The result is a pattern that resembles field lines. While the general pattern will always be the same, the exact position and density of lines of filings depends on how the filings happened to fall, their size and magnetic properties" ALL in all what I interpret from this explanation is that the iron filings in a sense become like two magnets sitting side by side with their poles oriented the same so that they tend to repel one another... I would absolutely love to know just how many field lines a particular magnet or electromagnetic gives off, that would be sweet, like is the number in the hundreds, thousands, etc. for say a small 1 cubic inch magnet.

essentially magents are warp drives in basic terms, now put a maget attach a magnet inside that coil and it will try to accellerate.. pulling the coil with it, and essentially this is warp so the magnet isnt really moving..

He never mentioned the amount of voltage that was applied to the coil. Was it 120 V? He just said that he was going to apply current but wasn’t specific as to the voltage source. Just thought that information would’ve been helpful. Other than that the demonstration was incredible. Thank you!

Great presentation, curious do the pieces of iron once aligned with the field begin to follow and move with direction of the field?
@electricandmagneticfields23143 жыл бұрын
They would, but there is enough friction between the iron filings and the plastic that they don't. This friction is why I had to tap the glass to get the iron filings to rotate and orientate along the field lines. Here is an example where they do, kzbin.info/www/bejne/h5K9YZtta71pmpI

@@electricandmagneticfields2314 another good one thank you. I’d love to see this with electro magnetism possibly a coil around a tube. Fascinating. I assume this would be much like a rail gun works, pushing force through the tube one way inside and on the outside in the opposite direction but less focused energy. I wonder how far this forces could be pushed and to what further applications

Everyone saying we should do this at school but tbh, I would prefer to do more experimental practicals, these are pretty intuitive and do not really need a practical to demonstrate. I would much prefer the challenge of "who can be the first to make a working induction cooktop" and do not allow the students to access Internet. We did that once and it was really interesting

In your 1st experiment with the multi-turn loop of circular wires, if you reverse the polarity of the current, will the field circles go in the other direction around the loops? From the positions of the iron fillings in the video, I can NOT tell which direction the loops are circling the wire? Secondary question: If you put a VERY high CURRENT, LOW FREQUENCY AC current through the loops (ignoring the high current burning up the wire), will you see movement of the iron filings switching direction with the AC? THANKS FOR THE GREAT VIDEOS!
@electricandmagneticfields23145 жыл бұрын
Yes, switching the direction of the current will reverse the direction of the magnetic field. Yes, if the frequency was low enough so the iron filings could follow the AC signal, they would flip back and forth with the frequency of the AC signal.

@electricandmagneticfields23143 жыл бұрын
The friction with the plastic holds the iron pieces in place. That is why I had to tap the plastic to get the iron filings to rotate. You can see that happens when the filings are in a liquid like this example of the magnetic fields around a bar magnet kzbin.info/www/bejne/h5K9YZtta71pmpI
