Using an electrical contact material for blowing an arc

Use of a material comprising a matrix of conductive metal and magnetic entities representing between 8% and 80% by weight of the material comprising magnetic phases hard to blow an electric arc between two projections of electrical contacts of which at least one comprising said material, characterized in that said magnetic entities are initially non-magnetized and they have been magnetized with an average orientation after, defined by the direction of a magnetic field applied to said material.
