Hysteresis & magnetic retention | Magnetism & matter | Physics | Khan Academy

The magnetic field inside a ferromagnet lags the vacuum field, and this lagging is called the hysteresis. Let's explore this hysteresis curve of ferromagnets.

U can't even imagine how many videos i have seen to understand this chapter but nowhere was i able to understand, neither in my coaching class nor from the videos and finally i found ur videos and finally understood this chapter whether its about diamagnetic, paramagnetic, ferromagnetic or its hysteresis loss....u r so amazing sir that I can't even tell u in words...thank u very much sir ❤️... finally I'll sleep well tonight 🎉thank u.....god bless ur soul sir✨

Why address him as "sir"? You're not in a conventional classroom. Why don't Indians stop being cringe on internet. Btw, I totally agree with what you said about his videos.

[@insidegeniuslab]

@@jdsaaa66767 ‘cringe’ STFU. if you are finding politeness and respect terms cringe, and commenting so rudely then the problem here is you trying to act edgy and cool on internet. and besides the teacher is indian too. if you care about indians so much, next time just see & scroll unless it's a real issue to be worried for

[@zezozezo1323]

Thanks for your efforts, in transformer the magnetic core is used to just strength the primary magnetic field lines means increase it's density or the core is produce it's magnetic field lines also and so the secondary windings is being linked by the combination of primary windings magnetic lines and core magnetic lines?

Sir, a kind request , can you please finish the part 1 of 12th physics before the half of june would be helpful for our boards as well as jee,neet

[@CatFish107]

Thank you Mahesh! I have been curious and perplexed by the concept of hysteresis with regards to the user defined paramters of certain digital functions in a synthesizer module (Expert Sleepers Disting Mk4), and have vague memories of the term coming up in a controls and instrumentation class.
I may have missed paying adequate attention that day, as I seem to lack an understanding of the core concept.

[@CatFish107]

Is there computer assistance for drawing those curves so smoothly? Do you use a drawing tablet?
It appears the straight lines snap to horizontal and vertical nicely. These are very nice blackboard results, however you make them.

Best explanation

[@muhammadhuzaifa4158]

B is magnetic field inside the ferromagnet
And Bo is outside the ferromagnet
We can change Bo by changing the current flowing through the ferromagnet

B in = mu r×Bo, but it was susceptibility × Bo, and if we remove susceptibility to mu then it'll Bo+BoUr

[@griefinnub3745]

Amazing video! You explained it really clearly. Thank you! Though, I have one question: When we decrease B_0, won’t there be a back EMF like in the case of a paramagnetic when we put a magnet near it?

[@satabdikakati5759]

Yeah there must be some emf when we deceased the magnetic field.. I think that back emf induced in the specimen probably contribute to the internal magnetic field...

ua-cam.com/video/peurIC9nCZM/v-deo.html

[@jatinbhatt7826]

Sir please clear the confusion between *B* and *H* . If H is the external magnetic field then why we use *B* for magnetic field due to current carrying conductor in most of the text book .

[@mohammadzaidqureshi2063]

●B is a magnetic flux density, and
● H is a magnetic fields strength .
●B= it's a magnetic flux passing through perpendicular a unit surface area.
●H = it's a magnetic intensity at a X (point) is the force acting on the unit N-Pole placed at X (point).
【H= m/4πu d^2】

[@jatinbhatt7826]

@@mohammadzaidqureshi2063 Then we should use H in bio savert law right! Why we are using B there?

[@alexyuri_94]

what happens if, after I reach the coercivity point (where B = 0), I increase the external field towards the positive direction instead of going further down to the negative? Will it follow the same path it took from the first quadrant to the second or will it be a new path?
