    Do you want a general solution, or have you been given, eg., m=(m1,m2,m3), r=(r1,r2,r3), or have you specific values for the vectors m and r?

    Either way, do the cross product first, then divide by the scalar magnitude, then apply the curl function.

    hi J77

    Thx for your reponse.. appreciate your advice...

    In fact, the solution to the above is given as attached... I can't seem to derive to the stated form... :cry:

    Would really appreciate if any guru can shed some light... :redface:

    Quick reply, but to me the transformation seems to lie in using Lagrange's formula:

    [tex]a\times(b\times c)=b(a\cdot c)-c(a\cdot b)[/tex]

    ie. "BAC minus CAB"
