n.

c.1300, “incantation, magic charm,” from Old French charme (12c.) “magic charm, magic, spell; incantation, song, lamentation,” from Latin carmen “song, verse, enchantment, religious formula,” from canere “to sing” (see chant (v.)), with dissimilation of -n- to -r- before -m- in intermediate form *canmen (for a similar evolution, see Latin germen “germ,” from *genmen). The notion is of chanting or reciting verses of magical power.

A yet stronger power than that of herb or stone lies in the spoken word, and all nations use it both for blessing and cursing. But these, to be effective, must be choice, well knit, rhythmic words (verba concepta), must have lilt and tune; hence all that is strong in the speech wielded by priest, physician, magician, is allied to the forms of poetry. [Jacob Grimm, “Teutonic Mythology” (transl. Stallybrass), 1883]

Sense of “pleasing quality” evolved 17c. Meaning “small trinket fastened to a watch-chain, etc.” first recorded 1865. Quantum physics sense is from 1964. To work like a charm (figuratively) is recorded by 1824.

v.

c.1300, “to recite or cast a magic spell,” from Old French charmer (13c.) “to enchant, to fill (someone) with desire (for something); to protect, cure, treat; to maltreat, harm,” from Late Latin carminare, from Latin carmen (see charm (n.)). In Old French used alike of magical and non-magical activity. In English, “to win over by treating pleasingly, delight” from mid-15c. Related: Charmed; charming. Charmed (short for I am charmed) as a conventional reply to a greeting or meeting is attested by 1825.
charm
(chärm)

One of the flavors of quarks, contributing to the charm number—a quantum number—for hadrons.

A charmed particle is a particle that contains at least one charmed quark or charmed antiquark. The charmed quark was hypothesized to account for the longevity of the J/psi particle and to explain differences in the behavior of leptons and hadrons. See more at flavor.
