Electro magneto field visibleo scope: A device to view the field lines

One of the main features of electrical engineering is the field lines. But a major drawback lies in these field lines - Lack of its visibility. There are no proper devices to view these field lines. This is a design of an instrument to make the field lines visible. The principle used in this design is PIEZOELECTRICITY. A 4×3 LED display is fabricated in this design which will help in viewing the path/shape of the magnetic field lines of any magnet.
