I am trying to calculate the magnetic field of an experiment with the apparatus but my values are way too high and i cant figure out what i am doing wrong

I am using the formula B = 0.7155NI/R

N= 130
I=1.82
R=15cm=.15m

calculating this i get 1128.6 which is too much of a value for the magnetic field, any help would be appreciated

What units are your equation in? Look here for the formula in SI units
