I was literally trying to understand this for like two days. And here I am understanding in few minutes... This video is a lifesaver thank you!!

[@emilygreen2436]

How do you know so much science? In awe. Thank you!

[@icegod4849]

@Nikolai Eliseo yo thats crazy! I saw two b̶o̶t̶s̶ I mean totally normal and real people comment these exact same things

[@arshisid47]

This really helped. Thank you.

[@sofiadeychoudhury3724]

This is such a good explanation!

[@Dinerlegacy]

Hey Bozeman Science I am really happy watching your videos and i would love you to talk (if you want) about electromagnetism like information transmission and atenuattion. LIke fields and waves.

[@valdocarvalho603]

Thank you for this rich and educational video 😁

[@johnmastroligulano7401]

Thanks always helpful.

[@mevrickneal2101]

Thank you for this brilliant information

[@Nice69]

Great video!

[@wassilykandinsky4616]

"What's the purpose of having these tiny magnets within the magnets?" Well, these tiny magnets think by themselves: Our purpose is to align ourselves parallel. Big magnets however think differently and believe their purpose is to align antiparallel.

[@ytrew9717]

But where these magnetic domains come from? Do they correspond to the little cristall/granuls that form when the melted metal solidify? And why the domains of magnet keep pointing on the same direction (why their electrons keep spining in the same direction)?

[@alfredjaniten1648]

If a 12 coil to produce a field, then if I charge up a photo flash coil and discharge through a standard 12 volt magnetic coil, would the Gauss be higher? Or is the Amperage through a coil the answer through a coil? A high voltage capacitor may be better as volts and amperage are discharged at the same time.

[@pjljbl]

Thanks this helped me with my kids science project

[@MatheusSilva-dragon]

Awesome! Thank you!

[@emeryselner7882]

Thanks! Great video

[@gamingcanidaesam9381]

Amazing i understood pretty well

[@toheebubolajiolabiran2124]

Educative video, how do i let those dormains face only the sides and ignore other magnetic field ?

[@abib1487]

@3.03 ,after the formation of a domain why have the poles been inverted

[@sanjaydubey3887]

This was fabulous.. I knew more😄 than my book..!!!!

[@rashamahmoud3166]

Thank you so much for this video😊l

[@rapidecho5705]

thanks helped me in homework

[@aiswaryasathian966]

Its very nicely described..... 😇

[@MakingVidsBreh]

How does this relate to the direction of electron rotations and biot-savart law?

[@examp7556]

Please reply, does electrons fly in magnetic field to produce current in a wire?

[@hannahalexis6741]

THANK YOU :)

[@SUMIT-EDITZ]

It's very nice video

[@gargievyas8804]

The vedio just cleared my confusion.

[@Holmnielsen-]

are the domains and domain walls determined by the grain structure of the magnet? Do magnets have grain structure similar to steel?

[@agastyachowdhry3218]

what in the world is that?

[@foxeongaming1576]

does the magnetic field exchange protons?

[@GOODBOY-vt1cf]

thank you so much

[@ConnorHorsley]

so helpful!!

[@kellyzhou8681]

could you please explain more, like why could this happen?

[@Sophie-fs6ot]

Thank u mr.

[@e9ib]

With which this domain exactly formed???

[@tanmarcus6361]

I have a question at 3:51 he said “put the iron in an electric field “ how does the magnet produce an electric field ?

[@GerasimosArtelaris]

Even though magnets can create electric fields, in this case I believe he meant to say "magnetic field". When he repeats it in 4:02 he says "magnetic field".

[@charliejohnston1978]

The electro-magnetic forces in the domains is not magic, the individual atoms have their own EMF charges that are normally random, but in a polarized domain situation the atoms are all aligned, which creates the non-random domain force and direction of that force is approx. uniform through out the domain.

[@josipaskoriciskra4987]

I have a question: is magnetic domain same as magnetic dipole?

[@46_rajworlikar24]

Thankyou Bro👌

[@Riteshkumar-kg4zy]

Actually I have a doubt.. Even I have done that experiment that breaking of magnets, but I observed a different observation. As you told the magnet's pieces should attract on each other after the breaking, but I observed that they repelled on each other. I didn't get to know why.

[@Riteshkumar-kg4zy]

Can you answer me.

[@niamhmulligan5820]

Sorry dude, no idea.

[@aliqwe4541]

Thanks ;)

[@ObiTrev]

Can you explain Magnetic Bubble Memory?

[@DigimonDNASavers]

How does a magnetically hard material 'retain' its magnetism more than a magnetically soft material? While I do know of the hysteresis loop that tells us WHAT is different between say steel and iron with regards to maintaining magnetism (Reminance) after magnetising or de-maganetising a material, It does not explain what exactly is the key thing that steel has and rather iron does not and HOW these materials are able to have such properties even though steel and iron is fairly similar with only one being an alloy.

[@scottd7222]

Bloch Domain Wall is the impenetrable barrier below our flat realm magnetic torridal field. Its 8 miles unde the earth.

[@sasswe2078]

Thank you

[@megapunk1474]

dude u are genius

[@s_________th5483]

Why are domains not formed in paramagnetic and diamagnetic materials?

[@JihadAlAnsari]

Last a certain amount of time? I thought ferromagnetic materials form permanent magnets?

[@rebollidoheavengracer.9041]

Ferromagnetic materials can only be a permanent magnet by using electomagentic conduction. Ferromagnetic materials which you bring close to a bar magnet or a magnetized object, will only last an amount of time because it was only an induced magnetism.

[@ash2092013]

you are right and thereafter permanent magnets don't need electric power to maintain a magnetic field.

[@ripvanwinkle137]

Don't forget particle spin, the underlying reason this happens! Subatomic particle is a tiny magnet! Getting kids to understand this will help later on in physics or chemistry (like NMR).

[@deepdusto]

Your comment is very insightful. a) How could lightening align the Electron Spins in same direction, b) With electron spins aligned in same direction, to me this concept is puzzling, does this not imply that there should be only one pole and not north and south?

[@physicsdiva1871]

Great

[@audreytran3336]

this was like so ammaing thanks booboo

[@liamc8085]

he looks like roan the cleaner

[@ranjana_official]

thanks

[@taehyungishot3215]

have my igcse exam in few days

[@godssoldier9997]

I understand this is the same process used n the va.ccines,thats why people get magnetised. Still I am not vaccinated and never made a PCR, yet my entire body turned into a magnet. I have no idea how this reached into my body but I already know that are hundreds of people in the same situation like I am.We might have been poisoned by water, by food or by the air we breathe...Since you seem to understand the principle better than I do, my question is: how I demagnetise my body. I would really appreciate your quick answer. We don't know the impact over our bodies and brains, once 5G and 6G is on the go...we might get all fried out. If we survive the experiment we will be connected to the AI. This is a bio weapon and a bio hacking. You see Mr Anderson... there are a lot of "Smith" agents after us. Matrix was not intended to be a movie... was a documentary. And so was I am Legend. By now I hope you got my point and I hope you might have a solution too. Might save the lives of many people. Peace.

[@audreytran3336]

😁😁😁😁😁

[@sachmuch9644]

What are domain made up of...how these domains came into existence...??

[@bluegecko8321]

i dont know what a magnet is anymore

[@MDGupta-pr7nd]

confused

[@21gioni]

At 1:48 you have misinformation.

[@ghazi2582]

No one asked

[@ajjarindahouse]

then what is it?

[@21gioni]

Opposites attract, don't they? So if you break a magnet in half; why doesn't it simply snap back together again across the break?

[@ajjarindahouse]

@@21gioni they will join but not with the same strength initially as the atoms were bonded before and now they are not only the magnetic fields are connecting them

[@niamhmulligan5820]

Was it helpful? Nope, no clue what he was going on about most of the time.

[@examp7556]

Please reply, does electrons fly in magnetic field to produce current in a wire?
