Editing Magical objects in Harry Potter (section)

== Detectors ==

=== Moody's Eyeball ===
In the ''Harry Potter'' series, [[Alastor Moody]] lost his eye and replaced it with an enchanted glass eyeball during the First Wizarding War. With the eyeball, Moody can see through solid objects, invisibility cloaks, and the back of his own head. Following Moody's death in ''Deathly Hallows'', the eyeball ends up in the possession of [[Dolores Umbridge]]. When Harry infiltrates the [[Ministry of Magic]], he steals the eyeball from her office and buries it in the forest.<ref name=":0">{{HPref|book=7|chapter=21}}</ref>

=== The Marauder's Map ===
In the story, the '''Marauder's Map''' is a magical map of Hogwarts created by [[Sirius Black]], [[Remus Lupin]], [[Scabbers|Peter Pettigrew]], and [[James Potter (character)|James Potter]] while they were students at the school. In ''Prisoner of Azkaban'', [[Fred and George Weasley]] give the map to Harry so he can travel to [[Hogsmeade]] through a hidden passageway. The map is a blank piece of parchment when not in use, but it becomes a detailed layout of Hogwarts when it is activated. It shows the locations of secret passages and instructions on how to access them. It also depicts the location of every individual at Hogwarts in real-time, including their movements.

=== Probity Probe ===
A Probity Probe detects hidden magical objects and concealment spells. Probity Probes are depicted as thin golden rods in ''Order of the Phoenix.'' After Voldemort's return, Probes are used to protect [[Gringotts Bank]] and to scan Hogwarts students for Dark objects.

=== Remembrall ===
A '''Remembrall''' is a small glass orb. It contains smoke that turns red when the person holding it has forgotten something.<ref>{{Cite web|date=2021-06-21|title=Harry Potter: Why Neville's Remembrall Turned Red|url=https://screenrant.com/harry-potter-neville-remembrall-red-reason/|access-date=2021-07-27|website=ScreenRant|language=en-US}}</ref> It does not tell the holder what has been forgotten. Neville Longbottom is sent a Remembrall by his grandmother in ''Philosopher's Stone''.

=== Revealer ===
A Revealer is a bright red eraser, used to make [[invisible ink]] appear. It first appears in ''Chamber of Secrets'' when Hermione tries to make hidden writing appear in Tom Riddle's diary.<ref>{{Cite book |last=Rowling |first=J.

=== Secrecy Sensor ===
A Secrecy Sensor is a Dark detector that looks like "an extra-squiggly, golden television aerial". It vibrates when it detects concealment and lies.<ref name=":3">{{Cite book |last=Riphouse |first=Acascias |url=https://www.worldcat.org/oclc/63888263 |title=The Harry Potter Companion |publisher=Virtualbookworm.com |year=2004 |isbn=1-58939-582-4 |location=College Station, TX |pages=247 |oclc=63888263}}</ref> In ''Half-Blood Prince'', every student and owl entering Hogwarts is inspected with Secrecy Sensors to ensure no Dark objects enter the school.

=== Sneakoscope ===
In the ''Harry Potter'' universe, a '''Sneakoscope''' serves as a [[Dark Arts (Harry Potter)|Dark Arts]] detector.<ref name=":3" /> The device is described as a miniature glass spinning-top that emits shrill noises in the presence of deception, for instance, when an untrustworthy person is near or when a deceitful event takes place nearby.

=== Weasley family clock ===
The Weasleys have a special clock in their home with nine hands, one for every member of the family. Instead of telling the time, the clock reveals the location or status of each family member. The known locations are: ''Home'', ''School'', ''Work'', ''Travelling'', ''Lost'', ''Hospital'', ''Prison'', and ''Mortal Peril''.

In the sixth novel, all nine hands point to ''mortal peril'' at all times, except when someone is travelling. Mrs. Weasley takes this to mean that with Voldemort's return, everyone is always in mortal peril, but she cannot verify this as she does not know anyone else who has a clock like hers.<ref>{{HPref|book=6}}</ref>

Various fans have re-created the clock for their own families, for example by using [[geofencing]] for cell phones.<ref>[http://elitedaily.com/envision/real-life-weasleys-clock-harry-potter/1387519/ This ‘Harry Potter' Fan Made An Epic Real-Life Version Of The Weasley Clock]</ref><ref>[http://www.instructables.com/id/Weasley-Clock/ Weasley Clock in 9 Steps]</ref>
