WebBackground: Magnetic field inhomogeneity in magnetic resonance imaging (MRI) is caused by the inherent properties of the main magnet, external ferromagnetic components surrounding the magnet, and the patient itself. Significant deviations from magnetic field inhomogeneity can create artifacts in MRI images, thereby compromising image quality. Web14 aug. 2016 · The magnetic field generated by an electromagnet has been used in protein crystallization for several decades. The first electromagnet (NPS 60 TS, Nihon Kohmitsu Co., Ltd., Nagoya, Japan) for protein crystallization has a static magnetic field of 0.1–1.6 T (homogeneity ±1%).
