    The hysteresis loop will be bigger for the magnetic iron and smaller in the softer iron. Thanks for pausing for learners to give their thoughts before moving on.

    Hi Mahesh I really like the way you teach, but some of the content are missing like derivation of magnetic field, and it's analogy to electric field, I will really appreciate you if you will cover on those topics as well .

    @shashankhegde2244 ปีที่แล้ว

    Very nice video. Excellent way of explaining. However, one topic to discuss is, a permanent magnet in its fully magnetized form will basically have very low permeability as no external magnetic field can cause the change in internal magnetic field? Only with respect to magnetic materials, we can have this comparison and no with permanent magnets which has no influence on the Bo value applied externally. This is basically what i understand. Please correct me if i am wrong in understanding. Thank you very much

    Soft iron has low coercivity and high retentivity ?? Am I correct??

    Sir i think there is a mistake here in the vedio towards the last. Soft iron has high retentivity than hard (according to what in ncert 2nd last paragraph of permanent magnets topic chapter magnetism and matter).
    Sir 🙏you explained really so well that i could understand the topic and could ask a question 🙋.
    You are clearly excellent👍.
    please clear my doubt !! .. I have my neet exam.
    Please correct me if i am wrong❌ 🙏
