Autodidact of various trades, geek of several.





There are probably two types of coders; the one who took up this craft before he knows it’s a quadzillion dollar industry, and the one after.

comment Is a superconductor really a super conductor?
@anna, I mean did we actually observed 0.0000000... up to like 200 decimal places? Because if we did, we can say it's practically zero. Or did we actually observed data for only ~10 decimal places?

comment Is a superconductor really a super conductor?
@anna, When you say "epsilon delta relationship", do you mean "yes, exactly 0.000000000 resistance is possible" or do you mean "no, we can never get exactly 0.000000000 resistance"?

comment Why doesn't the magnetic field of a coil “cancel out”?
As such, is it true to say that the brown arrow was drawn wrongly, and should have been drawn as the green arrow in: i.stack.imgur.com/EZYHc.png ?

the green arrow shows the field going out of the page from the top, and entering the page from the bottom. However, the brown arrow shows the field going out of the page from the bottom, and entering the page from the top. That's two opposite directions isn't it?

It should be named Ohm's paradox instead of Ohm's law.

@Waffle'sCrazyPeanut, what do you mean by "very basic" question?

Look at i.stack.imgur.com/CsZPJ.png . Isn't the brown arrow contradicting the green arrow?

@mikhailcazi, Why does the image shows a net "downwards towards me" field then? (look at the 5 arrows indicating the magnetic field)

comment Why doesn't the magnetic field of a coil “cancel out”?
@mikhailcazi, I'm not saying they ever point upwards. I'm saying why doesn't the "downwards towards me" field cancels out the "downwards away from me" field?

Exactly what I'm trying to say. I can understand the arrows for the blue section. But look at i.stack.imgur.com/MZbK5.png ... Isn't the image contradicting us for the red section?

comment Why doesn't the magnetic field of a coil “cancel out”?
(The image was blurry, I've made it clearer. See i.stack.imgur.com/MZbK5.png ) Yes I can understand the blue section. But in the vicinity above the red section, why does the image show it downward and into the page? Shouldn't it have been downward and out of the page?

comment Why doesn't the magnetic field of a coil “cancel out”?
This new image shows the subsection of the loop: i.stack.imgur.com/xmcgt.png . The image shows the direction of the magnetic field as downwards and towards us when the current goes to the left (bottom part of the wire colored blue by me). I can understand that. But why does it show the magnetic field has the same direction (downwards and towards us) when the current goes to the right at the top part (colored red) of the wire ?
