# Is it possible to construct a bigger permanent magnet from smaller ones?

I'm trying to find a way to construct a bigger magnet from smaller ones. It seems like there is a way to be able to do it at least as far as I've read. I'm having trouble understanding how that would work if it is possible though. Say I have two square magnets and I want to make a rectangle magnet, if you put them side by side so that North is touching North and South is touching South. This would create a magnetic field with a split in the middle of the magnet wouldn't it? This would produce a different magnetic field than just making a new larger magnet, right?

If you model the magnet as a magnetic dipole, you could use a formula like this one and do some numerical calculations by adding two identical fields shifted by a distance $$\Delta r$$.
