I appreciate that you feel this way, but the mechanisms behind exactly which neural circuits are activated by TMS are simply not yet fully understood.

From 2024:

> Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-cleared treatment for neuropsychiatric disorders with broad potential for new applications, but the neural circuits that are engaged during TMS are still poorly understood.

Again, different question. We know, fundamentally, how TMS causes stimulation/suppression of neural activity, and it does not require magnetoreception. Look at it this way: we don't fully understand how SSRI's cure depression, but we do know their primary target and that their mechanism of action is mediated through that primary target.
