Parallel flux

  1. Feb 23, 2010 #1
    Hi

    If we have a Y shape iron and we put a Permanent Magnet N pole at the bottom leg of the Y in such that it will saturate it. would the top ends of the Y also be saturated. what if instead of 2 we have 20 branches where flux can go. what is the saturation will be like at one branch?

    thx

    No the top ends of the "Y" wont saturate as they will each have only 1/2 of the saturation flux density.

    BTW. Since you don't specify then I'll assume that all legs of the Y have the same cross sectional area. Note that typically the "Y" would be connected to some form of yoke to form a complete magnetic circuit.

    Then, why the H-B curve does not take the cross sectional area in account?

    OR should I take the value of B and half it to get the saturation in the the branches?
