conceptually accurate, technically wrong. electrons are not attracted or repelled by magnets. they're oriented by them, and they flow along field lines. its a convenient design feature that in this case they move as described.
This confused everything I’ve understood about AC generation. It was my understanding that current only flows in a traveling magnetic field. So. In your example when the North Pole magnet is closely approaching your 12 o’clock winding it will start generating a counter clockwise current, it will hit its peak as the N flux cuts across the first side of your 12 o’clock coil. When the North Pole is in the middle of the coil there is no current. As the North Pole continues to travel now away from the 12 o’clock coil it produces clockwise current or the same current as if one introduced a South Pole. Some where as North Pole hits 1 O’clock the current in phase one goes to zero again. So a full cycle in phase 1 happens from an North Pole moving from 11:3O to say 1:30. Not all the way around. What am I missing?
Hey bro, I mean this sincerely. Thank you, for breaking this down simple and stupid. I needed this explanation for how three phase works. I am finally capable of understanding how alternating current actually works. Thanks again.
What I understand is it gives fast power per time since the angle is much lower, even it says 120 because 120 degree is higher than 90 degree, but paradox so 90 plus 30 degree, so 90 degree represents 2 phase, so the time rate between 90 degree of 360, which divide of 360 is 4, so it is 4 times per second compare to 120 degree represents 3 phase, so the time rate between 120 degree of 360, which divide of 360 is 3, so it is 3 times per second compare to 120 itself, so lower number is gap diameter is lower, so lower number is better, so like I say paradox because it represents geometry number which the more numbers there is, the faster rate of time, per power and higher than phase 1 base on formula of divide of 1 that is even, so square root of 1 is 1, so, it is combine of distance and time, so basically it is geometry which it is stationary and dynamic at same time, so the square can't roll, but circle can, so lower surface area which cause higher motion, so it reduces frictions, and gain power, so it is good shape, so that means it can be higher number so the ratio of different degree is lower so the time is higher and power is higher, so why 3, not 4 and so on base on circle which it is frictionless, constant, and less work to create, and beauty, so. So, also the ratio of nearby is higher than in lower degree number, so it causes stationary for magnet power which close to N and S, so the output power is constant per time, so it shifts base on frequently per time, so the power is constant which it is not as high as if the phase is lower. So, higher phase reduce the power of input so output is higher and easier from input's point of view. So, less time for charge and discharge which there is leaving and returning. So, basically for lower phase is higher frequently of input power, well, the higher frequently which you show for grid system is one plane, so higher frequently means it will be dynamic as it moves back and forth, but it doesn't, so one plane frequently is base on amount of nearby of lines so gap diameter per time. So, by circle is spin is closer for degree to degree, but by one plane it is close to gap diameter that means in the line above is a magnet that can be feel by another magnet in another line. And also for application that is lower in power base on 120 V, so it is not as clear explanation. So, 2 add up, so positive and negative, which cancel out which two curve meets. So, it is different from three phase which it doesn't means because N and S is 180 out phase, so that means it is equal to 180 out phase, so it cancels out. So, the three phase part which more than 2 as opposite to phase that is 180 out which two different plane, above and below, so in middle that is 120 degree, so need to add, so in total 360 of three 120 degree, so each magnet is 120 degree in total, well, not really because it is in circle of circle, so 120 of 360 of three 120. So, by itself that is one which it is 360 as 180 of one side that is one magnet. So, the shift of 360 that is 1/3 for one is 120, but 120 shift is depends by another magnet in rotate of three single magnet in 360 degree. What I see base on series of lines that is red, blue, and yellow, so the red getting input as highest power which there is a *, then it goes it zero, which it doesn't show zero which it is one line that goes down, but curve down, so it would be accurate to say process to zero from 120, 110, and so on, so 90 degree shift as it changes from 120 to 0, so per 1 degree down from 90 degree to 89 as section that is 120 divide 89 to 1.348314606741573 and subtract to result: 118.6516853932584, and so on to zero, right? So that is discharging, so the next line which it is blue line that is connect to N which it is returning to gain as charging *, so each N section of lines is a star, so the magnet change to center of NS, which it causes stationary per time, then returning per time by S that is discharging. So, the gap diameter is 120 degree per time, per motion of magnet shift in process of time. The application of home is one for each plug, so the plug represents 3 per time. As mention above for time and speed. So, 120 degree per time, per less frequently input from source of power. So, since it is about power that means the application can't handle higher power or It is not about higher power, but higher power, per time, which application needs higher speed, so it depends on application that can handle high speed, so per second is higher, so the phase is higher, so degree is higher to cause gate of power, per time is higher, which gate open so it is leaving that is S part, so same gate that is open so it is returning that is N part, and in between that is N/S, so it is close which the voltage is 0, so current is constant and instant in no time, so voltage cause current to return or to leave. So, gate is the volt. So, constant stationary volt is better than constant dynamic volt that is in your view it is beyond your condition viewing, so it is less than 1/4 or more second, so it will explode if there is constant returning, so it is not balance by returning to leaving and in between which it rotates. Constant N, constant S, or constant N/S. Constant N/S is better. Or N/S means zero current, or there is constant current since N/S is constant which it is middle that current is stationary, so not zero as it won't be a star to see. So, stationary current represents non-power? Or current is depends by magnet itself that means it is not non-power, but constant power, but as magnet rotate so the power leave or return. So, it is not non-power but it is more like electricity people do not have know how to make magnet stationary or they do because it means money for them, so it is selfish since when the power leave, you pay more for it to return. So, before of possible confuse myself further, so you answer, then I will answer since it is not fully explanation or if it is, but take bit thinking and other stuff or too fast as except other to understand
Hi TechTrainerNJ Team, is it possible that your animation is wrong? Between 5:29 and 5:31 is no change of flux in the coils (during the transition of the magnet from the LHS to the RHS of the coil) - So the Volt-Meter is supposed to show 0V instead of max Voltage. In a Wikipedia article below there is a change of direction when the magnet points to the coil... de.wikipedia.org/wiki/Datei:Simpel-1-faset-generator.gif Can you check and let me know please?
@@Ayrix06 there's a bunch of three phase videos from the engineering mindset and they have 2/3 of their animations incorrect, which is mind boggling. I think the intuition is: if you pretend the magnet is in the coil, Lenz's law makes the coil into a magnet. The "coil" magnet stays fixed, the other rotates. When it rotates, when the magnets match the orientation of the "coil" magnet, those are the zero points of the sine wave. When the bar magnet is 90° to the "coil" magnet, that's when the flux difference is peaking (or troughing). I think Feynman lectures may have a diagram... Can't recall.
Actually, I don't think you need Feynman. If you go to any (stupid) textbook that does that silly ideal AC generator and makes a single coil of wire rotate in a perfectly uniform magnetic field, it uses the similar arguments I had above, I think you get there. I really, really hate the textbook example because it'd be insanely hard to make that setup, and second it doesn't make the leap from this silly ideal setup to how generators are actually made (even if rotors have self-excited electromagnets instead of permanent magnets)... But I digress.
@@smokeybobca yeah i got you. I noticed the same that there are a bunch of animation videos which are incorrect (i had have also commented the engineering mind set videos but response yet). As you said, it’s mind boggling and I wasted so much time with it
Thanks for explaining a.c & 3,phase supply so clearly & how it relates to the diagram.American homes get 3 phase supply? We don't hear vibrations in sump pumps, refrigerators & the condensing unit.
Well he screwed up graphically, right around 4:30 trying to say that line one is at 0 current when the poles are at 3 and 9 o'clock... but at the same time, clearly the graph shows it at peak negative current...this is confusing...on the other examples hes got it correct.
Indeed yes. The diagram is also incorrect, because it shows a gap alternately between the 3 sine waves; but there is never a time when there is never a gap in 3 phase. Plus in some of the diagrams, shows a lesser voltage in the negative times than in the positive times. Finally, instructors often make something simple, VERY complex. But a truly good teacher will say, "In single phase there are 120 times a second where there is NO voltage (thus no power); whereas with 3 phase; there is never a time when there is no voltage (thus power is ALWAYS there during the entire 360 degree cycle). And THAT is why manufacturers always opt for 3 phase".
You guys have it the opposite I believe. The magnetic field is 0 at the north and south poles of the magnet, and strongest at the sides, so when the magnet is perpendicular to the wire, that's when electrons move, and when the magnet's N or S is at the copper, thats when the magnetic friend is zero therefore no current flows, aka no voltage is induced.
Yes, the lines of flux of the magnet "cut" through the conductor and induce a peak current when magnet is perpendicular to conductor, the alternating comes from opposite sides of magnet flux lines "cutting" through the conductor in opposite directions inducing current in alternating directions, thats how I learned as well
conceptually accurate, technically wrong. electrons are not attracted or repelled by magnets. they're oriented by them, and they flow along field lines. its a convenient design feature that in this case they move as described.
Yeah he's also showing the phase coils as a single wire instead of a coil?
So many technical inaccuracies it's unbelievable.
