Is it possible to make a one pole magnetic sphere? Answered

I know that naturally this doesn't exist. However what if i was to take two identical domed magnets and attach them to each other (not sure how I would do this) shouldn't this create a magnetic sphere with north on the outside and south on the inside. As shown in the picture.

A metal is magnetic because most of the magnetic mono poles have been aligned.

If you strap, forcibly 2 opposing poles together over time or as a result of mechanical effects one pole will reorientate and you end up with a N & S - Otherwise this would happen in nature.

Um, not quite. There are no naturally occuring magnetic monopoles (at the current limit of observation). Metals contain microscopic dipole domains, each domain having a north and a south end.

Ferromagnetic materials have most of their dipoles aligned parallel to one another, leading to a macroscopic north-south dipole field.

Paramagnetic materials, on the other hand, have their dipoles oriented randomly, so there's no macroscopic field unless and external magnet is applied.

Your description of the OP's application is quite correct, however.

Thanks for the clarification. I feel sure that's what I intended to say (not a physicist!)

A Star like our Sun can become a Monopole but that is because it works well
beyond our understanding of nuclear physics.
If I am wrong, I will delete this comment.
