Neodymium ball magnet field alignment

[r3born]

If a magnetised neodymium ball has a definite north and south point, could you slice the ball in two, and weld 2 "north" halves together, to create an entirely north ball? If this is impossible, how about designing a ball made in, say, a 3D printer, then embed it with small magnetised neodymium rods, all with the North point facing outwards? Would this give you an entirely/mostly "north" ball?

because magnetization happens at a very small level, when you cut a magnet in two, you actually get two magnets each with its own north and south.

Figured that would be the answer for the first approach, how about the second idea? how would the individual magnets interact with each other?

That would be a complicated NO magnet at all. There would be no B field outside the sphere.

How would said sphere react to a second, separate magnet?

It wouldn't.

It wouldn't.

Any chance of some elaboration? (if that's possible) Sorry for being a pain!

We have told you that such a configuration is not a magnet. What more can be said?

Hoping to learn the "why", only now getting into physics and there's still much to learn for me.
