1 Shock or excite (someone) into taking action:

2 (often as adjective galvanized) Coat (iron or steel) with a

From the etymology, we notice that tempt is testing to isolate a vulnerability (for the purpose of exploitation):
c.1200, of the devil, flesh, etc., "draw or entice to evil or sin,
lure (someone) from God's law; be alluring or seductive," from Old
French tempter (12c.), from Latin temptare "to feel, try out, attempt
to influence, test," a variant of tentare "handle, touch, try, test."
Galvanize is stimulating to protect against a known vulnerability:
1801, "stimulate by galvanic electricity," from French galvaniser,
from galvanisme (see galvanism). Figurative sense of "excite,
stimulate (as if by electricity)" first recorded 1853 (galvanic was in
figurative use in 1807). Meaning "to coat with metal by means of
galvanic electricity" (especially to plate iron with tin, but now
typically to plate it with zinc) is from 1839.
The standard metaphor of galvanize refers to the electrical process that moves dissolved metal ions to the surface of a metal object as a protective coating.
