When the current to the Inductor is cut off abruptly the Voltage across the Inductor reverses in sign (flips) the current remains continuous but decays like a decay voltage source. That voltage flip is important.

[@thomasmaughan4798]

1. The collapsing magnetic field is not called "Back EMF" it's just EMF and wants to push a current in the same direction that set it up. 2. Whether there's actually a CURRENT during collapse depends on the existence of a circuit. If you merely open the circuit, you cannot have a current; but in trying to push a current you are going to get a high voltage. This is what causes the spark in an automobile engine; it is the sudden breaking of the circuit by the distributor points (back when engines had such things). 3. In the special case of a superconducting coil, if you short circuit the inductor it will retain its magnetic energy forever. Such "superconducting storage rings" can store an enormous amount of energy and deliver it almost instantly.

Nice video about it. It helps. I just need a little further explaination on the opposite emf when the circuit is open. Why would it go in the same direction with the electrons?

[@iamsixsams]

Ok now i slightly understand it since i rewatch it. So you are saying, that since the magnetic field is now decreasing, the emf direction will now be the same with the elctrons, Am i right?

[@ENGINEERINGANIMATION]

Yes, you are correct.

[@kabandajamir9844]

So nice thanks

[@Keneethgurung]

Thank you so much ❤️

[@petermarkwood9077]

why does current flow if the voltage difference across the ac source is equals to the voltage source across the inductor(E0sinwt=Ldi/dt...you can see every book use this intital condition) in an pure inductor ac circuit????

[@ENGINEERINGANIMATION]

In this video, the inductor is connected to a DC power source. The current faces an opposition due to back emf , whenever there is a disruption in the current flow.Once the current becomes constant, there will be no back emf to oppose it. Hence, there will be a current flow. But in an AC circuit, the current is continuously changing.Because of this, the back emf will oppose it continuously all the time. So there will be a blockage to current flow.This blockage will increase with increased supply frequency.If the frequency is too high,the current will be blocked completely. Thanks for the comment!

[@thomasmaughan4798]

In a pure inductance without resistance, no current would flow because of the constantly changing voltage (hence current). This is the basis of a transformer that has no load on the secondary; you also have no load on the primary and it might as well just be an open circuit. loading the secondary prevents the magnetic field from completely opposing the source, and in this manner the load on the secondary is reflected to the primary and there's less opposition. No purpose is served just putting an inductor in parallel with either an ac or a dc source. An inductor is often placed in *series* with the load as it will oppose sudden changes such as a voltage spike on the mains.

Thank u sir ...it's so useful ..how inductor voltage leads the source voltage ???

[@ENGINEERINGANIMATION]

At the instant when the switch is opened, source voltage becomes zero.But in the inductor, the stored energy in the magnetic field induces a voltage in it. Now the inductor has a certain voltage,while the source voltage is 0. Thanks for the comment!

[@kanmanibama7953]

@@ENGINEERINGANIMATION thank u so much sir

[@thomasmaughan4798]

The inductor voltage is generated by a changing magnetic field. When establishing the magnetism, its growth creates a voltage that opposes the applied (source) for a while. The voltage cannot be greater than the source. When you open the circuit, the magnetic field collapses. It wants to produce a *current*, but it cannot since the circuit is open. Consequently it will produce a high voltage; a very high voltage and will produce a spark at the switch. If instead of just opening the circuit you switch over to a resistor, then you'll have a voltage across the resistor as the magnetic field collapses. The rate of collapse is governed by the current that is generated; if it can generate a strong current then the collapse will be slow because this current that it is generating maintains the magnetic field. The extreme case is a superconductor. If you short circuit an inductor that has a magnetic field, its attempt to decay the magentism produces exactly the current needed to build or maintain exactly that level of magnetism, so nothing happens. You have stored energy, a LOT of energy, in magnetism.

Dear...which one is more useful as an inductance. ..1watts or 0.5 watts or 0.25watts for the same value of inductor such as 10milihenrey for example! !!? Coz I have a private project n I want to order online ring colored inductor with value 10mh but there r 3 types of 10mh with different watts ... 1- 1w 2-0.5 w 3-0.25 w I need 10 mh with high inductance so which one of these 3 types is a high inductance? Thanks..😊

[@thomasmaughan4798]

"I need 10 mh with high inductance" Trick question? That's like asking for three different containers of 1 liter of water, which one contains 1 liter of water? Glass, plastic or metal? 10 millihenries is the inductance. Different watt ratings refer to how much current can you put through it before it gets hot and melts. "Fixed Inductors 10 mH Shld 20% 87mA 70Ohms" That inductor has resistance in the wire of 70 ohms. It is rated for up to 87 milliamps. AT 87 milliamps and 70 ohms, you get (E=IR) 6.09 volts. At 6.09 volts and .089 amps, you get 0.529 watts, or about 1/2 watt dissipation (heat).

Hey dude so it mean current start to pass through coil to another side of battery when the current reach max current or i can say when magnetic field no more expand right. And another question is that when current start to pass through coil cause of magnetic field can no longer expand do it have another magnetic field build up by current after the first max magnetic field collapse. ty

[@ENGINEERINGANIMATION]

You're correct on the first one. For the second question, the current produced by the collapsing magnetic field will not generate additional magnetic fields in the inductor. Thanks for the comment!

[@tou6093]

@@ENGINEERINGANIMATION no dude I mean the current from generator. What I mean is that is there another magnetic field build up to max after the first one collapsed by another current from generator.

[@thomasmaughan4798]

@@ENGINEERINGANIMATION "current produced by the collapsing magnetic field will not generate additional magnetic fields in the inductor." Incorrect. The inductor has no idea and does not care where or when its magnetism was created. As the magnetic field collapses, it tries to generate a current. IF it succeeds, the current so generated can and MUST generate a magnetic field! It cannot fail to do so. In the extreme example, if you short circuit the inductor with zero resistance wire, the current generated is exactly enough to continue generating the very same magnetic field that created it; in effect, the magnetic field cannot collapse. EVER. This is the basis of the "superconducting storage ring." it is simply a superconducting ring; imagine a million amperes of current in this ring, zero volts! Naturally a very powerful magnetic field. You can tap this energy very suddenly; megawatts from a single storage ring. www.sciencedirect.com/topics/earth-and-planetary-sciences/magnetic-energy-storage "The toroid with its induced persistent current will then have to be stored at liquid nitrogen temperatures over a period of several weeks. The current in the toroid is measured at periodic intervals over this time" www.imagesco.com/articles/superconductors/superconductor-energy-storage-ring.html Weeks! The current in the inductor maintains its own magnetism. This has implications for electric relays being sluggish to release, solenoids being sluggish to release, things like that.

How does polarity affect the flow of current? I wish you had explained that in different ways. Polarity on what plane? The flux direction is affected how?....And according to what change? Noobs like me could use a little more breakdown of topic and reinforcement. Polarity direction and its effect on current flow is still really confusing.

Can I ask a question

[@ENGINEERINGANIMATION]

Yeah sure.

[@ashrafuddin8798]

Please can you answer this question. Is the speed of light same in all direction . i.e:- I mean that the time taken by light to travel from sun to earth and from earth to sun will be same or not ......

[@ENGINEERINGANIMATION]

Sun emits photons in the form of light , which reaches earth in 8 minutes and 20 seconds. But earth only reflects the light. A photon looses some amount of its energy when it collides with a matter. So a photon which is collided and reflected from earth's atmosphere should have less energy than before. As a result, there will be a minor decrease in light's speed. So it would take a little more time to return to sun.

[@ashrafuddin8798]

But we have learnt that speed of light is constant and it was proved by Michelson Morley with his experiment Beam splitter , laser and 2mirrod

[@ENGINEERINGANIMATION]

Sir, Well explained with a clear animation. One doubt, when the current is changed to maximum value in a dc ckt, the source of current flow is due to dc source plus back emf induced. Right?
