    Hello everyone.

    I,m studying magnetic circuits and I'm stuck in calculating the mean path length of a squared core and circular one.I can't upload the circuits due to some issues in my PC.
    If any one could explain any circuit and generalize the idea that would be great.

    waiting for responds......thanks.

    if u have a specific article or explanation on effective mean path length calculations or derivations that would be helpful....Waiting for that.:eek:

    The conversion factor derivation for the ancient units of magnetisn are briefly explained in the last paragraph. The values
    you calculate can be converted online with the help of google etc. So, what more do you
    need to help you. posting an example of the problem you are working on and where
    you are stuck will us help you. Homework answering help is available other places
    and costs you REAL money.

    Effective mean path length for this core is ??

    The red line represents the longest path which a flux line could take to go round the core. The blue line is the shortest path. And in green is the mean length.
    le = (l_red + l_blue)/2
    l_red = 2*(10cm + 20cm + 5cm) +2*(15cm + 15cm + 15cm) = 160cm
    l_blue = 2*20cm + 2*15cm = 70cm
    le = (160cm + 70cm)/2 = 115cm

    And for this core

    lef = 32cm
