The linear momentum density carried by electromagnetic fields creates the hidden force acting on the displacement current between ends of an unclosed conductor with alternative electric current. This force compensates the self-force exerted by the unclosed conductor with zero thin. The magnetic field produced by displacement current does not contribute to the force acting on the conductor. The unclosed conductor can move under action of the self-force.

At small heights of cylindrical open conductor, the reactive force equivalent to the self-force becomes very large

Keywords: Abraham’s force, alternative current, conservation of momentum, displacement current, hidden momentum, self-force
