For the first time in this work, two new concepts in construction of magic square are considered. It is based on following two points:

Using small blocks of bordered magic rectangles.

Using algebraic formula (a+b)^{2}.

The whole work contains magic squares of even orders starting from order 6. This part is only for order 14. It is a revised version of the author’s previous work. For the complete work for the even orders from 6 to 20 see the links below.
