ABSTRACT:
The invention relates to an apparatus for location of an instrument or appliance having at least one magnet which produces a magnetic moment at right angles to the appliance shaft and can be rotated independently of the instrument or appliance. This results in a location system which allows precise location at an accurate time, determination of the axis direction and control of an appliance which is being operated in a channel or medium.
