Dear Mark,

    I sent you the message before I saw this one from you.


    Please see the pictures related to 7T coils (0,+60-60 deg) and 5T coils (+30,-30 deg) assembly simulated.

    The flux density and force distribution looks generally the same as in 5T+2T coils assembly but the peaks are more prominent now.
    Should I again compute the force in violet area as for the 5T+2T coils?

    Time spent 1 hour.



Best regards,
    Alex
