Some more 5th Ed questions

Yeah. Personally, I favor an approach where Arcana and Religion become a sort of supernatural Perception when trained.

This works. I really like what they did with it in Pathfinder second edition. There, Detect Magic is a cantrip, so you can use it as often as you like for only one action, but it only tells you if there is magic within the aura, not what or where.
