虽然ICE磁力计在Giacobini-Zinner彗星上的测量导致了一些意想不到的发现，如强烈的磁流体湍流，但它描绘的感应彗星磁层的大规模结构接近理论预测。虽然磁场线的强烈覆盖形成磁尾是预料之中的，但磁尾的结构也表明存在其他预测的特征。这包括一个弱的冲击波或压缩波，一个至少部分阻碍太阳风进入彗星电离层的电离层顶，以及一个磁场在电离层顶前方堆积的磁垒区。这些特征的推断位置使我们能够估计出中性粒子从原子核产生的速率（104 ×1028摩尔/秒），以及流入的太阳风离子和流出的彗星中性粒子之间的耦合强度。
While the ICE magnetometer measurements at Comet Giacobini-Zinner led to a number of unexpected discoveries such as the intense hydromagnetic turbulence, the large-scale structure of the induced cometary magnetosphere that it delineated was close to theoretical predictions. While the strong draping of the magnetic field lines to form a magnetotail was anticipated, the structure of this magnetotail also indicated the existence of other predicted features. These included a weak shock or compression wave, an ionopause which at least partially impeded the penetration of the solar wind into the cometary ionosphere, and a magnetic barrier region where the magnetic field was piled up ahead of the ionopause. The inferred positions of these features enabled the estimation of the production rate of the neutrals from the nucleus (≈ 4×1028 mols/sec), as well as the strength of the coupling between the inflowing solar wind ions and the outflowing cometary neutrals.
