Ampere’s Circuital Law
Inet : is the net Ampere Turns (AT) enclosed within N-turns conductor.
is the mean length of closed path (m
H : Field Intensity (AT/m).
FProperty that tell us how easily a magnetic
field can flow through a material
It is usually expressed in terms of relative permeability mr
The permeability is also the proportionality constant between an applied field intensity (H) and the resulting Magnetic Flux Density (B) : B = mH Þ m = mo. mr & mo = 4p´10-7.
