A spectroscopic imaging technique with high spatial resolution was used for the measurement of the static magnetic field homogeneity of RF coils. Measured magnetic fields of optimised and not optimised saddle-shaped coils were compared with the theoretical calculations. Results are in good qualitative agreement between calculated and measured magnetic field distributions. Quantitative disagreem...

The effectiveness of static magnetic fields (SMFs) in improving food freezing is a topic that, nowadays, raises substantial controversy among the scientific community. To shed light on this matter, new experiments, under well controlled conditions, were performed potato samples subjected or not to SMFs either 40–55 mT 150–200 mT, that is, approximately 1000 and 5000 times greater than Earth's f...
