Basically nerve signals are electric impulses travelling from the brain to body parts. What would happen if we move a magnet through cupped hands. Would it somehow interfere with the current of the nerve impulses?
Basically, nothing would happen. Your nerves aren't unbroken wires, nor are they coiled for maximum effect like in a generator. Nerves only transmit signals electrically within the neuron, between neurons you have a largely chemical process. Even with incredibly powerful magnets, such as in a MRI tube, or a particle accelerator, the induction would still be negligible, and we know this because these environments aren't instantly fatal, or even incredibly damaging. Errant electrical pulses in the body are very dangerous, especially to the heart and the brain, and it only takes a tiny charge before it's lights out.
