can we see magnetic field lines? if not how can we see them

If light is part of a spectrum why can we only see light and not the other parts of the spectrum? If we can only see light why can we infrared filters in a camera? And will we we ever evolve into creatures that can see other forms of energy too?
We can see the sun because it is glowing. How are we able to see the moon?
