Hi, I'm wondering if it's possible to attach two electrodes to my skin, about an inch apart from one another, and somehow flow current between the two so that that length of skin builds up sufficient magnetic charge to be attracted to a nearby (e.g., within 1 inch of skin) magnet. My goal is to leave a relatively strong magnet about an inch away from my skin and be able to turn on and off the current, in order to cause my skin to be pulled towards (or pushed away from) the magnet. I don't really know anything about magnetism, but is something like this even feasible? If so, what would the current signal have to look like (e.g., in terms of magnitude, frequency, etc.)? Thanks in advance! I wasn't sure if I should post this in the more advanced Magnetism section on this site, but if you think it makes more sense there, please let me know.

Skin is not a good conductor of electricity. To get sufficient current flowing to give the result you are looking for you would have to apply a seriously large voltage which would be exceptionally painful, probably causing burns and permanent scars. topsquark and neila9876 like this. __________________ ~\o/~

The appropriate and sensible replacement could be "magnetic field". The term "magnetic charge" or "magnetic monopole "is a senitive one. Royal pain in quire a long time, perhaps forever...In my own theory, it does not exist. The primary analysis about this is in my thread "charge moves relative to charge, one thing two aspects?" in the advanced section... topsquark likes this.

Thanks for your response! I think what you're suggesting is that I may have used the wrong terminology (or approach), and that I should instead try to generate a "magnetic field" rather than a "magnetic charge." Have I understood that right? How would one generate a suitable magnetic field to accomplish my desired result?

I can see this as an intellectual excerise, but why would you want to?

 Jun 6th 2019, 04:47 AM #9 Senior Member     Join Date: Jun 2016 Location: England Posts: 890 I guess that static electricity could be used , with the victim charged up (using for example a ) relative to a small metal plate which would be bought close to the skin. However, there is only so much charge difference that can be supported before sparks will start to jump across from the skin to the plate. I'm afraid that (in my opinion) it is unlikely that it would be possible to make a practically useful device of this type. __________________ ~\o/~
