| Research Abstract |
In a small permanent magnet, when heat flows in from the magnetic circumference, a magnetic temperature changes and magnetic field intensity changes. Magneto temperature is stabilized by making the magnetic circumference circulate through a phase change thermal storage medium as a coolant. In this research, it tried to raise the stability of a magnetic field by making the circumference of a neodymium magnetic body circulate through the phase change thermal storage medium which controlled temperature. The small permanent magnet which can circulate through a coolant for this purpose was manufactured.
The magnet circumference and a gradient field coil were made to circulate through a coolant, and magneto temperature was stabilized. As a result, the magnetic field was stable by circulating a coolant. On the other hand, when a phase change thermal storage medium was used for a coolant, the effect of stabilization seldom appeared.
