Magnetic resonance device has a sensor unit that determines the resonant frequency of the magnetic field in the vibrating main portion, and an evaluation device that determines the magnetic field strength of the resonant frequency

摘要

The magnetic resonance device comprises a measuring device (1a) for measuring the magnetic field, which is partially movably mounted against the restoring force of a magnetic field deflection-magnetic vibrating main portion (4). An excitation unit (10) excites the vibrating main portion to a free vibration. A sensor unit (14) determines the resonant frequency of the magnetic field in the vibrating main portion. An evaluation device (21) determines the magnetic field strength of the resonant frequency.
