Abstract
In a temperature control method for magnetic field components of a permanent magnet arrangement of a magnetic resonance system, temperature stability of the magnetic field components is achieved by maintaining the temperature of the two sides of the magnetic field components constant, with a difference being maintained between the temperatures of the two sides of the magnetic field components so that a temperature gradient is formed within the magnetic field components. Once the temperature gradient is formed, dynamic temperature stability is established within the magnetic field component. When this dynamic temperature stability is broken by thermal disturbance, the temperature gradient allows the thermal disturbance to be quickly transmitted to the lower magnetic yoke and is further transmitted to the outside through the base of the magnetic resonance system so that the thermal disturbance is smoothed and dynamic temperature stability is reestablished.
