Can an Electromagnetic Collar Block Pain During Medical Procedures?

AI Thread Summary
An electromagnetic collar could potentially block pain during medical procedures by preventing electrical signals from nerve endings in the affected area from reaching the brain. This device would cause temporary loss of sensation beyond the collar, allowing doctors to operate without causing the patient intense pain. The concept suggests that after the procedure, normal sensation would return, with only mild numbness experienced. Flexibility in the collar's design would be essential for comfort and practicality. This innovation could enable awake surgeries on limbs without pain.

When someone gets hurt or infected, its usually very painful when the doctor works on that exposed area. The only reason why you feel the pain is because the nerve ending shoot electrical signals to your brain. Would it be possible to devise an electromagenetic collar that goes around the arm or leg that prevents any electrical stimulation your nerves shoot from going past the collar. Granted, you would have total loss of your body past the collar, but that's just until the doctor stiches you up. Afterwards, you would regain use and only feel the numbness normally felt after a cut, but not the intense pain during. It would mean they could operate on your arms/legs while you're awake and you wouldn't feel a thing!

You could thread the limb around a ferrite bead - they would have to be pretty flexible though.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
