ELECTRICAL POWER TRANSMISSION AND DISTRIBUTION
As we know Ampere's law states that the magnetomotive force (mmf) in ampere-turns around a closed path is equal to the net current in amperes enclosed by the path. Mathematically is written as (1.3). mmf ³H x ds I (1.3) W here H is the magnetic field intensity in At/m, s is the distance along the path in meter.
