Description
This paper presents the design and simulation of miniaturized permanent magnet configurations for Nuclear Magnetic Resonance (NMR) applications where compactness and field quality are critical. Traditional NMR systems require large and costly equipment to achieve high magnetic field uniformity, which limits portability and broader diagnostic use. We investigate compact magnet geometries, including H-type and Halbach arrays, evaluating their field strength and homogeneity. Special attention is given to the trade-off between device miniaturization and achievable field uniformity, a key factor in measurement sensitivity. Through computational modelling, we establish a framework for quantifying and optimizing magnetic field homogeneity, providing design strategies relevant for portable diagnostic instrumentation and potential applications where in-situ, non-invasive measurements are required.
