    SMATH software
    Opis:
    This paper presents software that can be used for educational purposes – teaching students to perform the analysis of electric circuits [1]. Programmes created in the SMATH system [2] make it possible to solve exercises on electric circuits and constitute an interesting tool supporting the teaching process. The fact that the students can form their own electric circuit structures, with a preview of the equations and the solutions of these calculations, offers to them an interesting learning alternative.

    Opis:
    The paper presents the results of the analysis of the possibility of detecting ferromagnetic objects (ships, submarines, mines, etc.) by using two scalar magnetometers. By using two magnetometers of high sensitivity (in the order of magnitude of pT/Hz0,5) placed at a distance from each other and operating in a differential system, it is possible to detect ferromagnetic objects from a distance. It is necessary to compensate for the error code to synchronize the work of the two magnetometers. Ferromagnetic object’s detection by using two magnetometers requires proper configuration of the devices.

    Opis:
    Electrochemical processes take place in a metal object immersed into sea water even if an anticorrosive coating is applied [1]. As a result, flowing field appears around the object. There are naval mines between many other objects situated in the sea. Naval mines can be put in the seabed in order to be more difficult to detect by sonars. Such a mine is located on the line demarking two environments of different electrical conductivity. The results of a computer analysis of the influence of seabed’s electrical conductivity on the electric field’s disposition around a mine model are shown below. Also, a naval mine detection system based on the FPGA circuit is presented.

    Opis:
    A ferromagnetic object, located in the Earth’s magnetic field, changes the distribution of that field. By measuring such disturbances it is possible to detect the object and destroy it. To conceal the object, a special winding is placed inside its ferromagnetic shell, which function is to eliminate the disturbances in the distribution of the Earth’s magnetic field. A thin walled ellipsoidal shell made of ferromagnetic material are examined as the object model. Coils are placed inside the shell and their function is to generate a magnetic field, which eliminates the effect the shell makes on the distribution of the Earth’s magnetic field in the surrounding area. Such a procedure is called magnetic masking and the winding used for this purpose is called the masking winding. The possibility of building the masking windings for the ferromagnetic ellipsoidal shell, situated in a magnetic field transverse in relation to its major axis, is also examined. Masking of a thin-walled ellipsoidal ferromagnetic object located in the longitudinal magnetic field is described in the article [1]. Investigating the possibility of masking of objects in a transverse magnetic field presented in this article will allow for a comprehensive assessment of a possibility of masking thin walled ferromagnetic objects of elongated ellipsoidal shape. The solution of Maxwell’s equations, which describe the magnetic field distribution caused by the ferromagnetic shell presence in the Earth’s magnetic field, are applied. Furthermore, the ability of selecting coils, which fully eliminate the perturbations of the magnetic field outside the shell are proven.

    Opis:
    A steel-hulled ship in sea water produces an electric field around itself. The source of this field are electrochemical processes and ship’s cathodic protection. The analysis of the electric field around the ship is important by the reason of the ship’s identification and counter-mine protection. The paper presents a simplified model of the ship’s multisource electric field, which allows to calculate the electric field distribution in the so-called distant zone around the ship in an approximate way using a PC, during time lasting from few up to several dozen of minutes.
