The magnetizing force (H) for a circular conductor is given by:
\(H={I\over 2π d}\)
where, I = Current & d = Distance
The flux density (B) is given by:
B = μoμr × H
μo = Absolute Permeability
μr = Relative Permeability
Calculation
Given, I = 100π A
d = 10 cm
\(H={100π\over 2π 10× 10^{-2}}\)
H = 500 AT/m
For air, μr = 1
B = 4π × 10-7 × 500
B = 6.28 × 10-4 AT/m
