since , B= ¥Ni/L
CONSIDER,
¥ permeability const.
i Current
N Turns
l length

on substituting values, B= ¥2000 i/50×10^-2 , B=¥40×10^2i

also, flux=L.i here L= SELF INDUCTANCE

Also, flux= B A (area)
A = π 4

finally , flux= BA = ¥4000i
and, flux = Li are equal
therefore,. ¥4000i=Li
hence,
(self INDUCTANCE)L = 4000¥
here,¥= 4π×10^-7
