Perfectly shown without many words - that's I really love

[@kshitizpratapsingh7300]

This dude is underrated

[@cg-physics-global1021]

Thanks man 😁😁

[@skh4113]

Exactly!!

[@PeterLakatos-kq5fk]

finally someone explained it upline and practically thank god for you man

[@cg-physics-global1021]

I'm glad when it helps 😇

[@murad._umed4339]

Bro made me understand it in 2 mins Thank you very much

[@cg-physics-global1021]

You are welcome 😊😉

[@PinkeySuavo]

nice, it randomly popped out. I always understood that electromagnet works like that, but never managed to imagine the magnetic field when changing from single wire to the coil. So nice to see it, it makes more sense now, thx

[@cg-physics-global1021]

You are very welcome. And nice to hear, that my videos randomly pop out 😁

[@FatherFatherJohn]

Thank you man. Visually explained a lot to me 🙏🏾

[@cg-physics-global1021]

That is very nice to hear!!

[@Thedoublechamp]

One of the greatest videos on how magnetic resistance works 🎉

[@cg-physics-global1021]

Thank you 😉

[@Bwup]

absolutely wild this is possible, i look at these with new vision now, thank you

[@cg-physics-global1021]

ok, that's good to hear!

[@ronsinclair619]

Thank you. Told me a lot of what I wanted to know.🙏

[@cg-physics-global1021]

That is very good to hear 🙏

[@MasterPlan265]

the best explanation i’ve seen!

[@cg-physics-global1021]

thank you!

[@Johny40Se7en]

Thank you very much. Helped a lot with something I was trying to picture 👍😊

[@cg-physics-global1021]

I'm glad to hear that!

[@dhyana029]

It's awesome. Please make a tutorial on Inductor as it's the most confusing topic for many.

[@cg-physics-global1021]

Thank you very much! To your request, I made this video, maybe it helps: kzbin.info/www/bejne/fKKshJuDgLZ8sNE

[@success_2721]

👍Superb n Perfect video 😍😍😍😍😍

[@cg-physics-global1021]

Thank you 😊 😇

[@omebankinvesting7685]

Thanks. You made me understand🙏

[@cg-physics-global1021]

You are very welcome ☺️

[@rhodium8505]

the music / sound in this video is so nice

[@cg-physics-global1021]

Is it? Thank you very much 😁

[@pasantmohamed8059]

This only what made me understood !!

[@cg-physics-global1021]

That's great to hear 😊

[@ogtayguliyev4299]

Thankkkk youuu a million😍

[@cg-physics-global1021]

You are very welcome! I hope it helped 😊 😇

[@BentleyGT10]

Brilliant, thank you!

[@yato-4628]

Thanks a lot for explanation ❤. I want to ask a question how do they discovered that when a coil subjected to the current it will cause this effect?

[@cg-physics-global1021]

You are very welcome 😊😊 That was the danish physicist mr. oersted: kzbin.info/www/bejne/m5nUfJaplq59i5o And mr. Faraday discovered a lot of the technical devices, whereas Mr. Maxwell had the mathematical equations.

[@deshan224]

Best video i found 🔥

[@cg-physics-global1021]

Thank you!

[@BILBO1]

Thank you!

[@cg-physics-global1021]

You are very welcome ☺️

[@suredra1350]

Thanks sir good

[@cg-physics-global1021]

Thank you ☺️

[@ramzeneger]

Awesomeness!

[@cg-physics-global1021]

Thank you 😊

[@qal4real372]

im 5 years late but thank u for the explanation :)

[@cg-physics-global1021]

You are welcome

[@eyupozturk4408]

Thank you, it was very descriptive. So, does a different winding direction of the wire change the direction of the magnetic field?

[@cg-physics-global1021]

Thank you too 😊 Yes it would! There is a rule, that you can determine the direction of the magnetic field. But I don't know the english name ...

[@benlee3545]

0:10 May I know which direction the current is flowing? Would be a perfect video if direction of current is included. Is it flowing from negative to positive left to right? or positive to negative right to left?

[@benlee3545]

Ok i saw your other video. it flows from left to right negative to postive.

[@cg-physics-global1021]

Electrons come from the minus-pole and go to the plus pole (attraction). But there is also other definitions of current: kzbin.info/www/bejne/mKWZcmh-n9mBqdE

[@ttm-2909]

Nice ..thank you.

[@cg-physics-global1021]

You are welcome ☺️

[@rajatjain7310]

Thank you 👍👍

[@cg-physics-global1021]

You are very welcome 😀

[@daveg1683]

Thank you

[@cg-physics-global1021]

You are welcome 😌😌

[@Sirtigereg]

Now run the south end wire back through center and send current down it

[@cg-physics-global1021]

Just a visualisation 😇😇

[@mohitlahri8395]

Thank you sir

[@cg-physics-global1021]

You are welcome 👌

[@huguesmassin8903]

So where are the north and south of the magnetic field when the wire is straight ?

[@cg-physics-global1021]

There is no north and south pole. That only happens in a coil. For a north and south pole, you need the magnetic lines to run like at a permanent magnet.

[@huguesmassin8903]

if there is a magnetic field there are polarities, right ? trying to shape it in my mind

[@cg-physics-global1021]

A clear north and south pole only exists with coils or a well build magnet. kzbin.info/www/bejne/fJ6yfXSsq8dpZ7c At the beginning, there is none.

[@owenanderson6126]

Question What would happen if I place ring magnets connected to each other inside the coil Oriented with the earth magnetic field south to north

[@cg-physics-global1021]

There are always several magnetic fields present. And the strongest one wins! But it depends on all of them, how the magnetic field is orientated.

[@cg-physics-global1021]

kzbin.info/www/bejne/jmiThKaHns56aNUsi=3Lt4da8av2X4NnyA&t=288 Here is an example

[@engineeringcom8311]

Thanks

[@cg-physics-global1021]

You are welcome 😃

[@Maria-sz1fc]

Hello, how come we generate electricity by moving a magnetic bat in and out of the coil?

[@cg-physics-global1021]

That is the principle of induction. It is shown in a simple way here: kzbin.info/www/bejne/fKKshJuDgLZ8sNE With a coil, the effect is stronger

[@thundersfire]

I have a question , why we need a wire with coil in electrical circuit ?

[@cg-physics-global1021]

Sorry I don't quite understand. Could you explain this to me in more detail?

[@technical-apon-faraji]

We need these coils to make electromagnets.

[@boredengineeringentertainm4938]

By definition, electromagnet is a wire through which you pass currents to make it behave like a current. No currents, no magnetic field created. The number of turns in the coil therefore increases the field strength of the magnet

[@academiadaeletricidade]

Did you use blender?

[@cg-physics-global1021]

Yes I did ☺️

[@walkwithhim5258]

The sub titles are so small

[@cg-physics-global1021]

I'm very sorry, but you can set the fontsize bigger

[@Electro-coil]

And this is how i was made

[@ksyivan0818]

This is so hard omg

[@cg-physics-global1021]

What is hard?

[@ronaldoggha1801]

sus

[@AGeekNamedRoss]

At the beginning of the video, the current is flowing from left to right (screen orientation), yet the magnetic field lines are shown flowing from the bottom, towards the viewer and over the top. I think that this is the wrong direction, since it's not following the "curl right hand rule". The field lines should be shown flowing in the other direction. kzbin.info/www/bejne/gnLRg4eErNd5g9E

[@cg-physics-global1021]

The video is correct. If you go from - to +, you have to use the left hand. If you use the definition (+ to -) you use the right hand. In both cases the lines are correct.
