Well there are similarities in that they are both a form of induction. And lenzs law effects both. But there are 2 main differences between them. 1. The Back EMF as I described occurs at the same time as the EMF you apply from the power source. Whereas the Flyback voltage occurs when the switch is off, and therefor is on its own at that point. 2. The Back EMF is only ever equal to or less than the applied voltage, but the Flyback voltage can be hundreds of volts greater that the supply voltage.
As someone who have been observing Flyback and back emf for some time.. I can say that your explanation of the Flyback is correct but I have a different view of the transformer's back emf. We all know that the backemf helps to regulate the current in the inductor, when the back emf is equal to the applied voltage this reduces the current in the inductor, this also applies to the primary windings of the transformer. But immediately the transformer secondary is loaded, the current in the secondary cancel's the backemf of the primary which in turn causes the primary to draw more current Because the back emf of the primary is no longer equals to the applied voltage. The main difference between Flyback and back emf is that Flyback occurs when the current flow in an inductor is suddenly interrupted while back emf occurs when there's a change in Flux Back emf increases as frequency increases to the point where current is low. while flyback increases as frequency decreases to the point where current is high.
Very well done! Your distinction between flyback and back EMF (collapsing magnetic field inducing a voltage in a coil that is in the reverse direction) is correct! The electromechanical logic is simple to understand in backflow, when you consider that the north and south magnetic poles are pushed up in one direction by the current when created. And, like a child pushed up on a park swing falls backward by gravity, so too the magnetic field collapses back in the opposite direction when the voltage is removed!
Thanks. Yes you right about the analogy between Electromagnetism and Newtonian Mechanics. In fact the analogy goes even further since the equations of Electromagnetism were based on those of Newtonian Mechanics. Perhaps this would make a interesting subject for a future video, thanks for the idea.
This is a very interesting video. I appreciate the explanation of why a primary coil in a transformer conducts more current when the secondary is allowed to pass current... and that current flow in the 2nd coil causes a reduction in the inductance. Thanks for that perspective.

Consider this: 1) layers of thin aluminum sheet, each layer of metal separated by an insulation layer, in a horizontal orientation 2) vertical magnetic field up through the center of the stack of metal/insulator/metal/etc layers 3) 'eddy current' inducing coils positioned horizontally and radially to the metal/insulator layers 4) supply an RF frequency to the eddy current coils RESULT Right hand rule: vertical B field, horizontal RF current (E), in the metal. This E x B gives the Lorentz force, which coherently accelerates (oscillates) the charged particles in the metal It is known as a "Lorentz disk" and is the first device built by artificial gravity hobbyists. 'Upgrades' include: 1) circular planform (disk) for the metal/insulators stack 2) adjusting the size of the disk and RF frequency to create resonance/standing waves of the RF across the disk 3) working at increasing the Q factor (ie. increasing the build-up of amplitude at the peaks, aka the 'anti-nodes', in the standing waves on the device) This first device can be driven by a simple signal generator, a home-made RF amp to boost the siggen output, and store-bought aluminum foil. If you use storebought foil, its thickness lends itself to a 'skin depth' that insinuates an RF frequency of about 16.28Mhz, easily in the range of low-end siggens Next is learning to attach a 'floating' or a DC potential bottom plate so that the effect is unbalanced (a balanced artgrav field yields no motion, just like two equally-matched teams in a rope-pull contest) .
Well, I understand that there are some people who believe that a local and partial cancelling of the earths gravitational field can be achieved by combining high voltage (to cause a partial plasma) with a rotating magnetic field. Then one is into the realm of plasma physics and magnetohydrodynamics. The idea takes Einsteins Equivalence Principle, and takes it one step further to say that the force from gravity is not simply equivalent to inertia, but that they are actually the SAME! Then somehow combining fields as i described creates a shield from inertia (gravity) allowing flight. As for the engineering of the whole thing its too complicated for text messages i think. ua-cam.com/video/1JeeaZlYonc/v-deo.html

Why did the voltage reduce from 400v to just 20v in the case of flyback when resistor is connected? Did u connect a very high value resistor? What was the value of your resistor?
Great demo, thanks for that. The emf part of the demo is utilised in eddy current flaw detection in ndt and able to detect surface cracks in conductors through non conductive coatings. The secondary is the subject material in the ndt case though.
@@ElectricMonkeyBrain Not just these days. I worked on NDT by eddy current measurement in 1972 - my first job out of university. The simplest test gear used a bridge arrangement with two coils powered at 50Hz (mains frequency). One coil held a sample of a correctly annealed brake lever for motorcycles and the other had a conveyor belt that passed through it where the levers to be checked travelled. If the bridge came out of balance by more than a certain amount in one direction or the other, it triggered a solenoid that moved an arm which deflected the errant component off the main belt into one of two reject bins. The levers that were too hard would be likely to fracture and snap and those that were too soft would be likely to bend. The most complicated NDT equipment we made was for use in a steel mill where a continuous length of red-hot steel bar was made to pass through a large coil where we injected a low frequency (probably 50Hz) and a synchronised high frequency (perhaps 5kHz). The low frequency would penetrate some distance into the steel but the high frequency was confined to the surface layers (skin effect). A crack on the surface of the steel would be detected by phase-sensitive rectifiers as a significant shift in the relative phases of the two signals and that triggered a short squirt of engineer's blue onto the steel bar. Further down the line, the section with a the blue mark would be cut out, ensuring that the rest of the bar was free of surface cracks. All of that happened while the bar was still very hot and moving fast, which was a tough environment to do tests in. That bit of electronics hasn't changed much in 50 years.
Right. Yes I think I have heard of this technique. Using the skin depth is quite a interesting solution to detect differences between surface and bulk material. Actually I think its a huge field, I expect they use essentially the same method to characterize ferrites for transformers up to about 800Khz or so. I also used to do material measurement, but its was on the electric rather than magnetic side of things, and at much higher frequencies.
@@RexxSchneider I was going to say 'not just these days too', but anyway, Herr Foerster was making equipment to do ET back in the 1930s I believe. The real difference these days in most NDT methods is the addition of computing power to analyse results and improve the probability of detection. Eddyfi produce some interesting array systems for tubes etc.

Thank you, this is extremely interesting sir. What if I wanted to direct the collapsing field into a battery sir? What electronic components would I use? Thank you sir.
@@ElectricMonkeyBrain You should use a TVS Diode to capture the flyback. It has some interesting effects on the chemical behaviour of the secondary battery. If you use a battery relay to swap the run battery to become the charging / secondary and vice versa every 4 minutes, they both run for a very long time. Thanks for the video, it's one of the best explained I've watched. 👍
A good and important question. Its difficult to answer because there are literally 100's of different motor/generator configurations in existence, which have different effects. For example a GENERATOR made of permanent magnets and output coils should have very little voltage spikes because the output coils should have some diodes or bridge rectifiers which will take away this energy. A universal MOTOR for example, which has stator field windings which receive AC mains current, and rotor windings which receive current via carbon brushes will have voltage spikes in the rotor windings when the current through them is interrupted.
Well sort of, but the amount of heat produced will be very small. Ferrites are bad conductors, so they wont dissipate energy in the form of heat much. If you want to produce heat with a induction heater, the magnetic field should be inside a good conductor...like metal.
Weather you short out the secondary or not on a torodial transformer you will get back emf or flyback you will get a high spike in reverse weather you short out the secondary or not so what is the difference who shorts out the secondary any ways unless your using partnered coils bucking coils? A higher voltage spike makes the difference because you shorted the secondary.
The point of shorting the secondary was to show that when current flows in the secondary, it has an effect on the primary. And that the effect caused a reduction in primary inductance showing that the secondary current/flux opposed the primary. Thats why its called back-EMF.
hi. Magneto Hydrodynamics is a interesting, large and complicated field. Without knowing more about your specific design, its difficult to say. However, in general I would guess that you are trying to produce magnetic fields, which means you need coils. If you want to recapture some of the energy of those magnetic fields after you have used them, a simple diode into a capacitor would suffice, like I showed in the video. I would add that the speed of the diode is important. The 1N4000 series of diodes are very slow, and work good for 50Hz only. Something better may be a HER5000 series. To find really good diodes simple google "fast diodes".
