Kustības magnētiskajā laukā reģistrācija un digitālā apstrāde

subject

description

Darbā aprakstīta metode atsevišķu objektu magnētisko momentu noteikšanai, analizējot vides siltumfluktuāciju ietekmi uz to magnetoforētisko kustību. Izveidota magnetoforēzes iekārta un atbilstošs attēlu apstrādes algoritms. Parādīts, ka veicot magnētisku daļiņu kustības videoierakstu, iespējams noteikt to kustības trajektorijas un vidējos ātrumus. Vidējo ātrumu sadalījums katrai daļiņai ir atkarīgs no vides siltumfluktuācijām un var tikt aprakstīts ar teorētisku sakarību. No tās tika atrastas difūzijas koeficienta un vidējā kustības ātruma vērtības, kas ļauj aprēķināt objekta magnētisko momentu. Metode pārbaudīta, nosakot komerciālu magnētisku daļiņu magnētisko momentu dispersiju. Demonstrēta arī iespēja metodi izmantot kompleksas vides viskoelastīgo īpašību pētīšanā.
