What does it mean to isolate a magnetic pole?

Question

or how is it done?

Answer 1

Physics does not describe magnetic monopoles;
only dipole with a north pole and a south pole.
When you break an iron magnet, you have two magnets.

Answer 2

I believe what you mean is isolating a magnetic monopole, not a magnetic pole.

A magnetic monopole is a theoretical subatomic particle predicted by at least one Grand Unified Theory (usually SuperString theories). At this point, detection is much more important that isolating. Detecting one would go a long way to supporting some of the SuperString theories.
