Recently many products with gorgeous 3D patterns on the surface have been released as a kitchenware trend, and in particular, research is actively being conducted to implement 3D patterns and designs. Among them, 3D pattern ceramic technology using magnetic ceramic materials has the advantage of easily implementing 3D patterns using neodymium magnets and electromagnet jigs. However, there is a problem that there is a limit to the accurate shape implementation because the strength of the magnetic field varies depending on the size, shape, and arrangement of the magnets mounted on the jig. In this study, we conducted a study on the change in the magnetic field generated according to the gap distance between the jig and the frying pan. As a result, it can be seen that the closer the gap distance, the greater the strength of the magnetic field formed on the frying pan. When the gap distance is 0mm, a magnetic field strength of 15320G is formed, and when it is 4mm, it is half, 7660G, and when it is 10mm or more, it is formed close to 0G. Therefore, it was found that when the gap distance was 10mm or more, no magnetic field was formed inside the frying pan, and it was expected that the magnetic particles would form a 3D shape inside the frying pan at around 0 to 4mm.
