Inductor does not have storing capacity but it had the ability to resonate or dissipate surge effect by expand the surge current like rubber band and so regulate surge current to a degree

[@d614gakadoug9]

Inductors absolutely do store energy. Every switchmode power supply on the planet relies on that fact. However, unlike a capacitor you can't open the terminals of an inductor and have the stored energy remain. IF the inductor were made with a perfect conductor with no resistance and you shorted the ends of the winding you could maintain the magnetic field and stored energy. energy stored in an inductor = (L • i²)/2 where energy is in joules, L is in henries and i is in amperes

[@gkol69]

As a guitar player I would be interested to see how all these apply to guitar pickups which are basically coils wrapped around magnets. I know that the stainless steel guitar string is moving inside the magnetic field of the pickup and that generates voltage, but how is one pickup having different sound from another? How is each element contributes to the characteristics of the pickup?

[@alext8828]

I see that no one has answered you. Your question is basically why your pickups sound different. Among the reasons, the most significant factor is the placement of them. The neck pickup catches more low harmonics than the bridge pickup. You know that there are multiple harmonic frequencies on the moving string that contribute to the sound of the primary frequency of any of the strings. That is what makes an acoustic guitar sound different than a piano or a violin. Moving the pickups out away from the bridge allows lower harmonics to be heard. They seem to be filtered out by being close to the bridge or the nut. Does this help or hurt your understanding of the picture?

[@gkol69]

@@alext8828 All these you said I knew already, even that the neck pickup in a 22-fret guitar is under the 2nd harmonic. I wanted to know the physics of how the coil, the wire and the magnet contribute to the frequency pickup of the... pickup. Thanks for the response, anyway!

[@alext8828]

@@gkol69 ChatGPT says it's the string vibrating in the magnetic field that disturbs it and creates a variation in the current moving in the pickup coil. That's the very part that's vague in my mind. Here's their version: A guitar pickup is a crucial component of an electric guitar's sound-producing system. It works by converting the vibrations of the guitar strings into electrical signals that can be amplified and heard through an amplifier. Here's how a guitar pickup works: 1. **Construction**: A guitar pickup is typically made of a set of magnets, magnetic pole pieces, and coils of wire. It's usually mounted directly beneath the strings of the guitar. 2. **Electromagnetic Induction**: When you pluck a guitar string, it vibrates back and forth. As the string vibrates, it disturbs the magnetic field created by the magnets and pole pieces in the pickup. 3. **Changing Magnetic Field**: The vibrating string causes changes in the magnetic field strength around the pickup. This, in turn, induces a small electrical current in the coils of wire wrapped around the pickup. 4. **Electrical Signal Generation**: The induced electrical current in the pickup's coils carries the characteristics of the string's vibration, including its frequency and amplitude. This electrical signal is very weak and requires amplification to be audible. 5. **Amplification**: The weak electrical signal generated by the pickup is sent to an amplifier through a cable. The amplifier significantly boosts the signal's strength, making it loud enough to be heard through speakers. 6. **Sound Production**: The amplified electrical signal is then sent to a speaker, which converts the electrical signal back into sound waves that we can hear. Different types of pickups, such as single-coil and humbucker pickups, produce slightly different tonal qualities due to variations in their construction and the way they capture string vibrations. The position of the pickup under the strings also influences the tonal characteristics. The pickup is a critical element in shaping the unique sound of an electric guitar. Different guitars and pickup configurations can produce a wide range of tones, which is one of the reasons electric guitars are so versatile and beloved by musicians.

[@gkol69]

​@@alext8828 I already know all these! To make myself more clear, my questions are: 1. How each turn of wire inside the coil affects the frequency response of the sound? 2. How the thickness of the wire affects the frequency response? 3. How the inductance affects the frequency response? 4. How the width of the pickup coil affects the frequency response? 5. How the strength and the material of the magnet affects the frequency response? By frequency response I mean: Does it roll off high frequencies? Cuts off bass? Makes the harmonics of the fundamental note you play more pronounced? And how: Each turn rolls off 5Hz? 10Hz? Boosts the bass 3dB? 6dB? Different magnets with different strength boost all frequencies? If not, which ones? ...and so on.

[@jozsiolah1435]

Very important parts in laptops, phones, power banks. Inductive components remove the memory effect of batteries to reach higher capacity. The feature is locked, you won’t be able to use it. Laptops turn it in by discharging the battery in Bios. Bad batteries will be destroyed in Bios. Power banks turn it on when you charge with lightning cable, or if the phone is better type. Phones turn it on in the power menu, or if you unplug the battery for a few seconds. Car charger also switches it on. Later charging and discharging leaves it on. Laptop fan can fix a battery. Pc fan can fix a 12 v battery. If the component doesn’t have inductive parts, memory effect won’t leave the battery. A diode is in the batteries/ devices, removing the memory effect.

There is actualy a mistake made in this video. That is when the voltage is removed from the inductor, the current does "Not" reverse, it continues in the same direction through the inductor only the polarity changes, this is because the inductor has now become a generator as the field collapses. The rest is all fine with the video.

4:58 your animation appears to be wrong. the current should be opposite the feed current according to your graph at 5:54 since you show a reversed polarity across the inductor after removal of the feed current. also, your animation defies the right hand rule and the rule you stated at 2:32. you messed up.

[@sridharchitta7321]

The opposing emf produced by an inductor is a characteristic of the non-Coulomb electric field that is proportional to the rate of change in current causing a changing magnetic field. And that is Faraday's Law. The current is a result of the combination of an opposing Coulomb electric field and the applied field which is changing the current. The opposing Coulomb (C) field is a result of polarization of the inductor by the non-Coulomb (NC) electric field. So, the current is a consequence of the resultant field of the applied field and the Coulomb electric field in the inductance coil and is determined using the governing relation in conductors J = σE_net. If the resistance of the solenoid is very small, the magnitude of the two electric fields is nearly equal (E_C ~ E_NC). It is not possible in this post to discuss in more detail the formation of the Coulomb field when the current in an inductor is changed. Before learning Faraday's Law and its application to the operation of inductors, it will be instructive to understand Current, the conduction process and Voltage at the fundamental level as in the following two videos: i. kzbin.info/www/bejne/iHbWiJeabJukrsU and ii. kzbin.info/www/bejne/bnO0fpKurJeFnNE The last frame References in video #1 lists textbooks 3 and 4 which discusses topics on inductance and inductors in more detail using a unified approach and provides an intuitive understanding of inductive reactance. It also describes with sequential diagrams how an inductor develops the induced emf. Textbook 4 shows how the current lags the voltage across the inductor by 90 degrees for sinusoidal input voltages using sequential diagrams.

日本人です。日本語でスミマセン。この動画を見たので少しだけ私の感想を言わせて頂きたいです。日本語翻訳にて見ていましたが、本来インダクタなんてのには余り興味を示しては居ませんでした。ただ、コイルとか動線とかって考えでしかなかったのです。だけど、見ている状態並びに日本語翻訳では有るのですが、この原理を使うとテスラコイルが何だか見えてくるようなんです。インダクタの中には太い銅線を巻いたやつとか細いけど縦に巻いている様なのを見た時に、磁場とかを見た状態で通常で出されたりしていて売られたりしていますところの「テスラコイル実験キット」の様に思えたんです。どの様に説明したら良いのか少し判らないのですが、細い銅線でコイルを巻き、外側に太い銅線で又コイルを巻くって感じからすると、何となくですが小さなテスラコイルが出来てしまうのかな？なんて思いました。まあ、本当にラジオでもTVでもPCでも電気製品を使って居る場合、其れ等が壊れたと言って捨てるとか考えたりしている場合じゃないって思います。金持ちって人達はどうかとは思いますけど、貧乏をしている私なんかの場合は、他なんかの情報を得て其れに対して近いって思うことが出来た場合、其れを実験するしか無いって思います。金持ちって人達の場合は駄目になったら捨てれば良いって考えだとは思うんですが、貧乏をしている私に取ったら、宝の山かも知れないって事を感じました。ストレートに言うと批判が起きるかも知れませんので余り言いたくはないんですが、壊れたら捨てれば良いって考え方は余りにも「勿体ない事。」って思います。人間自体が其れを理解すると良いですね。

The Inductor converts part of the electric current (Q/t) to magnetic flux (BA) . The magnetic field (B) itself is not energy. Energy (E) is a product of the current (Q/t) and magnetic flux (BA). Thus E = 1/2 Q/t * BA. So B is just one factor of the energy equation. It is wrong to imply that B is energy or contains energy. It actually is 1/t or the reciprocal of time. The stronger the B the shorter the time and greater the velocity, acceleration, voltage and energy. Furthermore since E = 1/2 current * BA then for a given amount of E when B or BA is increasing current or Q/t will be decreasing and if BA is decreaing then urrent must increase. Simple as that

A wire absolutely does act as an inductor. It is a plague in circuit design, especially power distribution in fast digital circuitry. Even the inductance of a small surface mount capacitor can degrade the performance of the capacitor (a simple model is an ideal capacitor in series with an inductor in series with a resistor) The waveform shown at about 5:50 is not what you actually expect in an inductor. If the inductor is discharged at the start when a voltage is first applied across it, the current will begin at zero and rise linearly with time, it will not be curved as shown. The curve is what you would expect if you were to charge the inductor from an ideal voltage source through a constant resistance.

[@MyTubeSVp]

Why is this narrated by a computer voice ?

[@kenday7942]

If I didn’t already know what inductance was I certainly would NOT know after watching this presentation. It is one of the most confusing things I’ve ever seen. You do not need to state the NAMES of all the laws for people understand the CONCEPT (such as Lenz’s Law, and such). Whoever made this presentation should have taken a course in instruction. ALSO, If you use electron flow for current flow for everything ELSE you teach, then WHY suddenly switch to conventional current flow here to describe the ‘right hand rule’ when you could have just said use the ‘left hand rule for electron current flow’ to determine the direction of a magnetic field?! (Not sure why this is important for somebody to know to understand inductance in the first place, but in case you are still reading this by now, here is the definition of inductance: inductance is that property of an electric circuit that tends to oppose a change in current. It does the because whenever a current flows in a circuit there is a magnetic field generated. If current stops flowing or changes direction that magnetic field collapses and induces a current in the opposite direction, since the field is now moving in the other direction. This is true for a straight piece of wire OR in a coil - making a coil of wire simply concentrates this property into a smaller area, which causes a corresponding increase in the inductance. In a DC circuit once the current reaches a steady state inductive reactance is no longer significant because there is no CHANGE occurring. If you open the switch, the magnetic field collapses and induces a voltage in the opposite direction which tends to keep the current flowing (until the magnetic field has completely collapsed and there’s no more change occurring). Of course this is not the great explanation either because I do not have the luxury of using diagrams and illustrations and such in this comment section. IN SHORT, you tried to cover WAY too much in the short time allotted, which only leads to confusion of the audience. You also stated that if ryou stretch the coil out you end up with a wire “…which we all know does not act as an inductor ” That is totally incorrect. A straight piece of wire DOES act as an inductor - although a very small one and it does have a magnetic field around it, something else that you incorrectly stated.
