In this study, an observation vessel which could depict magnetic field distributions in threedimensionswas produced. The magnetic field observation vessel was made by putting magnetic fluid and water in a transparent square shaped glass container. Observation of both permanent magnet andelectromagnets was carried out. The movement of the magnetic fluid is different depending on the placement of the magnetic poles. The magnetic fluid showed a tendency to gather near each magnetic pole, when it was placed between the same magnetic poles placed face to face. On the other hand, the magnetic fluid collected between the two magnetic poles, when it was placed between different magnetic poles placed face to face. In most magnetic field observation devices, such observationis difficult. The results indicate that the magnetic observation vessel is useful in explaining the relationship between magnetic lines of force and magnetic force.
