Can someone with nondetection be picked up with detect magic? It seems to me that detect magic will sense a magical aura (perhaps abjuration or illusion) since it does not target the creature.

Also, I see nowhere that states that detect magic is a scrying sensor.

Scrying is non-targeted Divination. Why does it state this if nondetection would just work on it? Detect magic is also non-targeted, and not specified, so it would work.

    \$\begingroup\$ This is going to be nitpicky either way, but here is something fairly unrelated: while looking for more supporting material, I accidentally found out that you cannot cast detect magic on yourself if you are under the effect of nondetection (since detect magic actually targets self). Mind slightly blown. \$\endgroup\$ – J.E Jul 28 '20 at 13:21

I present two different, independent arguments, hopefully at least one is helpful.

Nondetection says it hides the target from divination magic.

Flavorful language in spell descriptions are rules too.

The description of nondetection says:

you hide a target that you touch from divination magic.

Detect magic is a divination spell, and nondetection says it hides you from it. Case closed.

Areas of effect may target creatures inside them.

Alternatively, we can make an argument that specifically addresses the relevant mechanics.

The Dungeon Master's Guide speaks of creatures inside areas of effect as "targets" in the section on combat:

If you would like more guidance, consider using the Targets in Areas of Effect table.

So when nondetection says,

The target can't be targeted by any divination magic,

it means that divination magic with an area of effect does not detect the creature who is under the effect of nondetection.

In contrast, the rules use the more specific phrase "target directly" when an effect is not an area of effect. Note the rules for total cover:

A target with total cover can't be targeted directly by an attack or a spell, although some spells can reach such a target by including it in an area of effect.

The point of these examples is to demonstrate that the rules respect creatures inside of areas of effect as "targets" and areas of effect as "targeting" them.

This answer goes into greater detail.

Mostly joke argument, but kinda for real.

Its called nondetection, obviously it defeats detect magic.
