摘要

a magnetic head for a dipping pool arrangement, in particular a dipping pool arrangement of a balance operating according to the principle of electromagnetic compensation of force,(a) with a housing (102), which has an interior (108) with a floor area (114) and a surface running vertically for this purpose; and(b) with a permanent magnet unit (110) located in the interior (108) of the housing (102), which has a permanent magnet (112) and a polar plate (120);(c) where the permanent magnetic unit (110) is provided in the housing (102) in such a way that a ring column to accommodate a diving pool (104) of the diving pool arrangement (100; 200) is formed between a circumferential surface of the polar plate (120) and the circumferential surface of the interior (108) of the housing (102),(d) where the permanent magnet (112) is glued to the floor surface (114) of the interior (108) of the housing (102) with the floor surface (114), a adhesive layer with a thick dK is formed between the floor surface (114) and the bottom of the permanent magnet (112); and(e) where the polar plate (120) of the permanent magnet (112) is connected to the housing by means of a rigid attachment device (118, 206) and is so positioned; that a bottom of the polar plate (120) is facing a top of the permanent magnet (112) and a gap with a specified column width dL is formed between the bottom of the polar plate (120) and the top of the permanent magnet (112).
