Manipulation with magnetic and electric fields

Sample: E_M_Feld2
Beads : Micromod, Sicastar-M SH 1,5µm
Video : 13-24_1-12_2-23
Area : 70,6 x 54,6µm (220x170+370+490)

In the beginning, a current of 80mA is applied to the inner thick line to pull the markers off the small line (two single markers and an agglutination of markers). But the magnetic force is not strong enough to break the sulfur bond. Then the current is turned off and after 90sec an electric field is applied between the outer electrodes.The markers directly move towards one electrode, so the electric field is strong enough to break the bond.
