A magnetic valve is proposed, in particular a fuel injection valve for internal combustion engines, which has a valve housing, a conductor coil mounted on a core of ferromagnetic material, and an armature which carries a valve body cooperating with a valve seat. The core has an inner cylinder and an outer cylinder, which are magnetically conductively connected with one another at one end face via a yoke. At the other end face, a circular-annular plate is magnetically conductively connected with the outer cylinder. The magnetic circuit is closed between the circular-annular plate and the inner cylinder via an armature, which has a plate-like element and a hollow cylindrical strut. The strut is located opposite the inner cylinder and with it forms a first air gap. The rim of the plate-like element of the armature is located opposite the circular-annular plate and with it forms a second air gap.
