sähköstaattisesti

Sähköstaattisesti is a Finnish adverb that denotes an action or process driven by electrostatic forces, i.e., by static electric charges and Coulomb interactions. It is formed from the adjective sähköstaattinen (electrostatic) with the adverbial suffix -isesti. The root terms come from sähkö- (electric) and staattinen (static).

In usage, sähköstaattisesti describes how something occurs due to electrostatic interactions rather than magnetic or dynamic electromagnetic effects. It is common in scientific and engineering texts to indicate that a process relies on stationary charges, such as electrostatically charged particles being attracted or repelled, or a process driven by electrostatic forces. Examples of contexts include particle handling, surface treatment, aerosol science, and various coating and printing techniques where electrostatic attraction or repulsion is exploited.

Relation to broader concepts: sähköstaattisuus refers to the property of being electrostatic, while sähköstaattisesti as an adverb refers to the mode of action. The term is mainly used in Finnish technical language and is less common in everyday language.
