低磁場之核磁共振比起高磁場之核磁共振，磁場均勻度要求較低，線圈建造成本較低，且訊號不受化學位移影響，可觀察化合物之分子特性。在實驗室環境下進行低磁場之核磁共振量測 ( NMR )，以 0.74 Tesla 之釹鐵硼磁鐵做為預磁化場，來增加樣品之磁化量，使 NMR 訊號辨識度提高。量測在不同主磁場下的 NMR 訊號，觀察主磁場的不均勻度對 FID 訊號之影響，藉以找出最適當之主磁場。利用核磁共振量測量含有 J-coupling 訊號之化合物，如：三甲基磷酸與三氟乙醇，觀察其原子核自旋交互作用對 NMR 訊號的影響。磁流體為一磁性粒子，將其加入水中量測會影響水的磁場不均勻度，因此我們量測不同濃度磁流體的水核磁共振訊號，由量測結果觀察不同濃度磁流體與自旋自旋弛緩時間 ( T2 ) 關係。
