I agree with all above formula.

If I'm not mistaken U=Uo.Ur why not user 1/Uo = 0.796x10^6.

Use this farmula
R=l/uA Here l= length,u permeability, a= Area
R= .07/(0.0014*4500*10^6)
R=l/uA Here l= length,u permeability, a= Area
R= .07/(0.0014*4500*10^6)

Lets relate Reluctance with Resistance,
R = pL/A, S = L/uA.
p=Resistivity u = Permeability
so,
S = .07/(0.014*4500* 10^-6) = 1111 At/Wb
R = pL/A, S = L/uA.
p=Resistivity u = Permeability
so,
S = .07/(0.014*4500* 10^-6) = 1111 At/Wb

Reluctance S=L/(MU*A)
