Abstract
In this paper the behavior of a finite magnetic fluid volume on a line conductor is investigated. Here we consider the problem of a magnetic fluid drop on a line conductor and the problem of a finite magnetic fluid volume on a horizontal plane near a vertical line conductor. The possibility of the fluid shape hysteresis for a cyclic increase and decrease of the current and of spasmodic drop thickness changes at certain values of the current is treated. Figs 7, Refs 6.
