Your formulation of this question is not accurate, but your conclusion is correct. In classical electrodynamics, there are no natural magnetic monopoles, and they cannot be constructed (look here). There are some speculative theories of matter that require monopoles, but none have ever been observed.
You can pick up any general physics text to learn about classical magnetism. For a less mathematical approach, you might try "Conceptual Physics" by Hewitt.
