does anybody know why the magnetic field for a single-layer solenoid of a point in the middle of the solenoid axial field is(adsbygoogle = window.adsbygoogle || []).push({});

H=[(4pini)/(10L)]*{[L+2x/[2(D^2+(L+2x)^2]^(0.5) +

[L-2x/[2(D^2+(L-2x)^2]^(0.5)}

where L is the length of a finite solenoid, D is the diameter
