I actually dont think, the Rodin Coils creates a Monopole, but the opposite Pole is sucked into the Coil. Its anywhere deep inside or even maybe outside where usual the other Pole appears. The winding itself should create usual a opposite Pole when they get powered.

Even when some claim, they have found now the magnetic monopole,
Magnetic Monopoles Detected In A Real Magnet For The First Time
i dont think it is really possible. Anywhere the opposite Pole will allways appear.
