Questions: Why can't I see magnetic fields?

The question is a bit disingenuous. I know that magnetic force and electrical force are the same force (electromagnetism) and that the wavicle (has wave and particle properties) that transmits this force is the photon.

We can sense photons, but in a narrow energy band, and frankly, our sensitivity is poopy (for examples, most of what we call colour is illusory (or reconstructed, depending on your point of view) ) and the resolution is terrible.

Wrong rant.

My real question is: How powerful would a magnetic field need to be to emit photons that fall in the visible spectrum - if that even makes sense.

P.S. I'm not worried about the damage such a field might cause to a person (for the purposes of the question, at least).
