Magus Arcana - Metamagic type question

[Khrono5]

This might be a dumb question since I haven't seen it posed on this forum yet, but if I choose any of the magus arcana that act as metamagic feats, do I have to choose which spell they apply to like the feats do when I prepare spells, or can I choose to apply the arcana at will when I see fit?

You use the magus arcana as you cast the spell.
