The invention relates to a kit (10) for a ball track (44). The kit (10) comprises at least one mounting surface (12), made from a magnetizable material, and at least one magnetizable rail part (20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40; 74; 76; 78; 80; 82; 84). The rail part (20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40; 74; 76; 78; 80; 82; 84) has circumferential narrow sides (47) and can be connected to the mounting surface (12) at a spacing (b, h) from the mounting surface (12) via magnetic forces with the aid of at least one magnet (14, 16, 18). As a result of the spacing (b, h) which is produced between the rail part (20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40; 74; 76; 78; 80; 82; 84) and the mounting surface (12) as a result of a height (h) of the magnet (14, 16, 18), a running rail (oL, uL) is formed by the mounting surface (12) and the circumferential narrow sides (47) for a ball (42) made from magnetizable material with a diameter (D) which is greater than a width (b) of the running rail (oL, uL). The width (b) of the running rail (oL, uL) is defined by the spacing (b, h) between the mounting surface (12) and the rail part (20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40; 74; 76; 78; 80; 82; 84). |
