  • 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.

    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?

    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.

      ●B= it's a magnetic flux passing through perpendicular a unit surface area.
