Magneettisella

Magneettisella is the adessive singular form of the Finnish adjective magneettinen, meaning magnetic. In Finnish, adjectives inflect for case, so magneettinen takes the adessive ending -lla/-llä, producing magneettisella. This form is used to express location on or at something that is magnetic or related to magnetism, with a following noun in the adessive case.

In practice, magneettisella appears in phrases such as magneettisella kentällä (on the magnetic field) or magneettisella levyllä (on a magnetic disk/plate). The adessive form signals a locational or situational relationship rather than a stand-alone property. For example, Laite toimi magneettisella kentällä, meaning the device operated within a magnetic field, uses the locational sense of magneettisella with the noun kenttä.

When expressing a general property or characteristic, Finnish typically uses magneettinen (e.g., magneettinen kenttä for “a magnetic field”). Magneettisella thus functions mainly to convey where or how something is situated in relation to magnetism, rather than describing its inherent quality.

Etymologically, magneettisella combines the stem magneettisen (magnetic) with the adessive suffix -lla, aligning with Finnish noun-adjective agreement and case-marking conventions. The form is common in technical, scientific, and descriptive Finnish, especially where spatial or contextual relation to magnetic phenomena is relevant.
