Type of External IronComputer FEM (finite element magnetics) models suggest the limiting factor for energy transfer is the magnetic saturation of the thin iron nail. This is inherent to the projectile itself, but we can reduce the saturation of the remaining magnetic circuit by adding external iron. Type of External Iron
Top View of Iron LaminationsThe drawing below shows the dimensions as measured from the transformer core leaves. This is included for documentation purposes, and will become useful if a computer FEM model is later created.
End View of Iron LaminationsThe drawing below shows how iron laminations are stacked to form the structure around the coil. The middle layer is made of the E-core sections, pressed tightly around the firing tube. The top and bottom layers are made from the straight iron strips. The existing holes are drilled through to accept the machine screws.
