Note: as magic() generates randomly, you will need to generate all of the magic squares of that size and compare each of them to the original matrix.

One test: calculate the mean of the numbers in the array. If it is not an integer, the array cannot be a magic square.
Another test: an array which is square and has all elements identical is a magic square.
A third test: magic squares are always two dimensional, not vectors and not three or more dimensions.
