  You detect Charm, Compulsion, and possession effects.
  You immediately detect the Strength and location of each such aura on all creatures in the area. You can attempt to identify the properties of each aura by attempting a Spellcraft check.
  In addition to noticing the targets of these effects, you can recognize when creatures in the area are using these effects on others by attempting a Sense Motive check as a Standard Action (DC = 20 + Caster Level). If you succeed, you can attempt a Spellcraft check to identify what magic it is using (even if the target is not in the area).
  Aura Strength: An aura’s power depends on a spell’s functioning Spell Level or an item’s Caster Level; see the accompanying table. If an aura falls into more than one category, detect magic indicates the stronger of the two.
 
Spell or ObjectFaint Moderate Strong Overwhelming
Functioning spell (spell level)3rd or lower4th-6th7th-9th10th+ (deity)
Magic item (Caster Level)5th or lower6th-11th12th-20th21st+ (artifact)

  Lingering Aura: A magical aura lingers after its original source dissipates (in the case of a spell) or is destroyed (in the case of a magic item). If detect charm is cast and directed at such a location, the spell indicates an aura strength of dim (even weaker than a faint aura). How long the aura lingers at this dim level depends on its original power:
 
Original StrengthDuration of Lingering Aura
Faint 1d6 rounds
Moderate 1d6 minutes
Strong 1d6x10 minutes
Overwhelming 1d6 days

  Each round, you can turn to detect charm in a new area. The spell can penetrate barriers, but 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt blocks it.
