Problem 2442. Magnet and Iron

(Inspired from Problem 112: Remove the air bubbles)

Iron (atomic number = 26) is strongly attracted by magnet. The input matrix contains some iron elements (26). I placed two strong magnetic bars above the top row and below the bottom row. What will be state of the matrix after the iron elements have moved due to attraction? Elements equidistant from both magnets will not change their positions.

Example:

 Input =

       1    26
       3    26
      26    26
       0     0
     -12   NaN
      26    26

 Output =
      26    26
       1    26
       3    26
       0     0
     -12   NaN
      26    26
