Abstract
A bistable magnetic wire has an electrically conductive wire coiled thereabout as to form, generally, a magnetic wire assembly which is situated in spaced proximity to a magnet; the opposite ends of the conductive wire are electrically connected to related output or receiving apparatus; a shield or shutter arrangement operated generally between the magnetic wire assembly and the magnet serves to cause the magnetic wire to be at times placed under the influence of the magnetic field of the magnet thereby resulting in the magnetic wire changing from one stable state to another state and in so doing inducing a voltage into the conductive wire to produce a pulse across the said opposite ends thereof.
