When a current passes through the coil, J, magnetic flux passesthrough the fixed pole piece, K, through the coil housing, L, then acrossthe small annular air gap, M, to the moving pole piece, F, and across theair gap between the pole faces near the center of the coil. Flux in the lattergap causes a force on the armature which tends to pull it and the valve
