[RPG] Can the Detect Magic spell detect an Antimagic Field spell


This is a duplicate of this question, but for a different gaming system; Pathfinder v1 vs DnD 5e. Also relevant, but slightly different is this question about intersection.

So the gist is, a wizard is sitting in the middle of an empty 50'x50' room. They have cast Antimagic Field on themselves (10' radius so well within the confines of the room with no obstructions).

Another character opens the door and doesn't trust the wizard with the wry smile and casts Detect Magic (30' radius, so big enough to reach the wizard 25' away but well outside the Antimagic Field).

Things within the Antimagic Field appear mundane, as per the spell description. But does the other character sense the abjuration spell itself?

Best Answer

You would not feel the presence of the field

This answer stated the opposite before, but upon further reading of the Anti-magic field spell I realized it was wrong.

As per Detect Magic's description:

For the duration you sense the presence of magic within 30 ft of you. If you sense magic in this way, [...], and you learn its school of magic if any.

Anti-magic field effect on spells:

Spells. Any active spell or other magical effect on a creature or an object in the sphere is suppressed while the creature or object is in it.

Areas of Magic. The area of another spell or magical effect, such as fireball, can't extend into the sphere. If the sphere overlaps an area of magic, the part of the area that is covered by the sphere is suppressed. For example, the flames created by a wall of fire are suppressed within the sphere, creating a gap in the wall if the overlap is large enough.

According to the description in Areas of Magic, Detect Magic's area of effect would be cut short the moment it reached the field, looking as though theres no magic there.
