What does attracter mean?
Attracter means one that attracts — something that draws people, objects, or attention toward itself. It is best understood as a variant, and markedly rarer, spelling of the more standard word "attractor," which serves the same function. In everyday use it can describe anything with pulling power, from a popular market stall to a charismatic personality. In mathematics and physics, however, the term takes on a precise technical meaning: an attractor (and occasionally attracter) is the set of states toward which a dynamic system tends to settle over time. In chaos theory, so-called "strange" attractors such as the Lorenz attractor illustrate how systems that never repeat themselves can still trace a recognizable underlying shape. Because the standard scientific literature overwhelmingly uses "attractor," writers are generally advised to adopt that spelling; "attracter" survives chiefly in older texts and as a straightforward agent noun built on the verb "to attract."
One that attracts; something that draws other things or people toward it.
"The free samples were the main attracter at the new café's opening day."
In mathematics and physics, a variant spelling of "attractor": a set of states toward which a dynamical system tends to evolve.
"The paper described the system's behavior in terms of a single stable attracter."
In this technical sense the standard spelling is "attractor"; "attracter" is rare in current scientific literature.
The plural simply adds -s, following regular English noun formation.
"The city's festivals act as powerful attracters of international tourism."
In chaos theory, a 'strange attracter' is the invisible shape a chaotic system keeps tracing — order hiding inside randomness.

Etymology of attracter
Attracter derives from the Latin verb attrahere, meaning "to draw toward," formed from ad- ("toward") plus trahere ("to pull, drag"). English adopted the verb "attract" in the late Middle English period via Latin and French, and the noun "attracter" was formed directly from it using the agent suffix -er, parallel to forms like "employer" or "inspirer." Its synonym "attractor" instead uses the -or suffix favored by Latinate verbs, which is why that spelling became dominant, especially in scientific contexts. Related words sharing the same root include "attraction," "attractive," "contract," and "detract."
How attracter is actually used
Attracter is considerably less common than the standard spelling "attractor" and appears mostly as an agent-noun formation from the verb "attract". Writers in mathematics and physics almost universally prefer "attractor". The spelling follows the general pattern in which Latin-derived verbs ending in -ate form agent nouns with -or rather than -er.
