In DC or direct current, the flux is constant. AC or alternating current is variable.

i) leakage flux is those flux which goes through the air and linkage flux is those flux whose go through the cell.

ii)leakage flux is the loss at flux but linkage flu is warning flux.

iii)leakage flux is cause of eddy current loss and linkage flux is case of copper loss.

The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)

when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux.

flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.
