    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✨

    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.

    • @GarthPrice-ej6bt
      @GarthPrice-ej6bt 2 місяці тому

      @potatochips4mee Primary clue occurs at 5:40 where the word 'retention' is used. At the very beginning - when the solenoid has never been powered - B(sub 0) and B(sub s) are equal at zero. The iron core has some random polarization - numerous norths, souths, easts and wests cancel out any kind of field just by being random. The very moment it is powered - then power is removed - the polarization will be altered, relative to its original state.
