I realised that, but believed it to be some sort of missusing of words. ANd the suposed correct solution is B(0,0593)=5.8E-4 T

The B field in a loop with current I is guiven by (at a guiven distance along the axis) B=(μ0 . I) (a^2/(a^2+z^2)^(3/2) If we have a continuos set of rings from 0 to 0.007 m, each with a current I= 1.07 A, what would be the B field in a point at 0.0593 m along the axis?

My approach was that a disk is a “infinite” number of circular loops with radius between the values of ‘a’

I everyone, I am atending a Master in Physycs Engeneering. Somehow late (I´m 50), but assuming to make some changes in my life. :)

I integrated B within the limits of a (from 0 to 0.007) the result was 3.64E-10 T and it was wrong. the correcto one would be 5.8 E-4 T and it is a major diference (aprox 1 million times ) what shoud I have done? Regards
