1) Magnetic stimulation delivered at acupuncture points / meridian points

• Yu HL et al., 2016. Magnetic stimulation at Neiguan (PC6) acupoint increases connections between cerebral cortex regions. Neural Regeneration Research. This is one of the closest direct analogues: magnetic stimulation was applied at a named acupoint on the Pericardium meridian, and the authors reported altered cortical network connectivity.

• Yuan J et al., 2021. Low-Frequency Magnetic Stimulation of Shenmen Acupoint Reduces Blood Oxygen Levels in the Prefrontal Cortex of Healthy Subjects. Chin J Integr Med. This supports the idea that low-frequency magnetic stimulation at an acupoint can produce measurable neurophysiologic effects.

• Yin N et al., 2022. Electroencephalogram Analysis of Magnetic Stimulation at Acupoints. This paper examined magnetic stimulation at several acupoints, including points on different meridians, and reported differential EEG/network effects by acupoint location. That helps support the broader idea that magnetic stimulation at acupoints is not physiologically neutral and may vary by meridian context.

2) Meridian-line or directional / polarity-related magnetic placement

• Jo HG et al., 2011. Electroencephalogram activity induced by magnetic stimulation at acupuncture point. Neurosci Lett. The abstract snippet is especially relevant to your polarity question: the study hypothesis and reported findings involved Heart meridian stimulation with different directions of line-magnet poles, suggesting that pole orientation/direction can matter physiologically.

• Jo HG et al., 2011. Effect of Acu-Magnetic Stimulation on Heart Rate Variability. This appears even closer to your “opposed polarity along a meridian” idea. The report states that stimulation with different directions of magnetic poles on the Heart Meridian produced significantly different HRV effects, supporting a role for magnetic orientation along meridian pathways.

• Liu YW et al., 2022. Analysis of Meridian Flow Direction by Electrical Stimulation Method. This is not magnetic-field delivery, but it is relevant to your “line/circuit” concept because it experimentally addressed meridian directionality and found that direction influenced the measured response current. That is a useful supporting analogue for any design theory based on vectoring or directional placement along meridian paths.

3) Multi-point / circuit-style acupoint combinations

• Zhang J et al., 2016. Evidence of a Synergistic Effect of Acupoint Combination. This does not use magnetic coils, but it is relevant to your “meridian lines and/or circuits” language because it supports the idea that combined acupoint stimulation can produce synergistic effects beyond single-point stimulation.

• Wang YK et al., 2020. preliminary RCT/fMRI study on primary insomnia. PubMed’s summary notes that combination of multi-acupoints might improve efficacy, which again supports the broader “circuit” or constellation concept, even though the modality was acupuncture rather than magnetic coils.

• Wang Y et al., 2016. Cerebral Targeting of Acupuncture at Combined Acupoints... This is another useful analogue for multi-point design logic: combined acupoints were associated with distinct brain-region effects.

4) Reviews tying magnetic stimulation to acupuncture-like methods

• Jun MH et al., 2015. Modern acupuncture-like stimulation methods: a literature review. This is a good umbrella citation showing that magnetic stimulation of acupoints sits within a recognized family of “modern acupuncture-like stimulation” methods.

• Colbert AP et al., 2008. Magnets applied to acupuncture points as therapy. This is a broader review of acu-magnet therapy. It is more about permanent magnets than powered coils, but it supports the historical and clinical precedent for magnetic stimulation at acupuncture points.

• Li J et al., 2012. Biophysical Characteristics of Meridians and Acupoints. This review summarizes biophysical studies of meridians and acupoints, including magnetic aspects, which is useful background support when positioning meridians as targets for measurable physical interventions.

5) Device-level analogues using electromagnetic acupuncture or magnetic coil delivery

• Oh SY et al., 2018. Efficacy and safety of electromagnetic acupuncture using an electromagnetic therapy stimulator (Whata153) for chronic low back pain: study protocol. This is relevant because it uses the phrase electromagnetic acupuncture and reflects formal clinical investigation of a non-needle electromagnetic/acupuncture-adjacent stimulator.

• Lo SF et al., 2023. Clinical efficacy of electroacupuncture-like magnetic therapy compared to conventional TENS in individuals with carpal tunnel syndrome. Scientific Reports. This is another strong bridge citation because it explicitly studies electroacupuncture-like magnetic therapy, showing the field is moving toward magnetic analogues of electroacupuncture.

6) Coil geometry / paired-coil literature relevant to your hardware, but not meridian-specific

• Older PEMF literature and later patent discussions describe biologic effects from fields generated by paired coils, including Helmholtz-aiding air-cored coils, and public patent text tied to PEMF discusses generator-driven pair coil systems and biologic responses. That is supportive for the paired-coil hardware logic, though not for meridian placement specifically.

• More generally, studies comparing different magnetic coil designs for peripheral nerve activation show that coil geometry changes stimulation behavior, which supports the plausibility that a conical coil is not just a cosmetic variation.

Bottom line
The literature supports these pieces individually or in partial combinations:

• magnetic stimulation at acupoints,

• orientation / pole direction effects along meridian-related stimulation,

• multi-acupoint synergy / circuit-style logic,

• hardware relevance of coil geometry and paired-coil delivery.
