V poslednee vremya spetsialisty, nauchnyy interes kotorykh nakhoditsya v oblasti biologii, meditsiny, geofiziki, geologii, tekhniki, sotsiologii, psikhologii i mnogikh drugikh nauk, udelyayut vse bol'shee vnimanie sopostavleniyu parametrov vneshnikh geomagnitnykh variatsiy s tendentsiyami sushchestvovaniya i razvitiya nablyudaemykh sistem i ob"ektov pod ikh vliyaniem, a takzhe posleduyushchemu analizu poluchennykh rezul'tatov. V osnove svoey etot interes neset v sebe ideyu togo, chto nekotorye sostavlyayushchie geomagnitnye variatsii (ili ikh opredelennoe sochetanie) s dostatochnoy veroyatnost'yu mogut neposredstvenno ili kosvenno vozdeystvovat' kak na biologicheskie, tekhnicheskie, geologicheskie i prochie ob"ekty v tselom, tak i na cheloveka v chastnosti. V rezul'tate chego iskazhennye normal'nye usloviya sushchestvovaniya rassmatrivaemoy sistemy, vynuzhdayut ee libo prisposablivat'sya k izmeneniyam okruzhayushchey magnitnoy obstanovki, libo prodolzhat' sushchestvovat' v ney v stressovom (neustoychivom) rezhime.
