PTF of Main at 26.00350 Amps = 0.0838 T
Pole Length = 0.08 m and gap = 0.0305


PTF of Main at 1 A = 36.4 G 
PTF of Trim at 1 A = 18.2 G

Remnant field with power supplies off = 8.2 G

I checked the pole tip field with the main at 1 A and then the trim at 1 A and the difference of the fields were (36.4-8.2)/18.2-8.2) = 28.2/10 G  = 2.82 
which very close to the 40/14 turn ratio of 2.86.
