So magnetic waves? Shouldn't those be called "electromagnetic waves"? What's new here? Just that they use a frequency that is transmitted well through the body?

- zamalek 11y agoA wire is an electric field with an electromagnetic field in the vacuum surrounding it. Chances are the same principle applies here: you'd have a magnetic wave in your tissues with a weak electromagnetic field around you. I'd assume that the "magnetic field" would be similar to (or the same as) the field present in ferromagnetic materials. Remember electromagnetism isn't really a "thing:" it is not a distinct field, rather its two fields that interact with each other. The electric field and magnetic field are still distinct.
- tobias2014 11y ago"The electric field and magnetic field are still distinct." This is not entirely true. In general it depends on your intertial frame what fields you see. See for example: https://en.wikipedia.org/wiki/Classical_electromagnetism_and_special_relativity#The_E_and_B_fields https://en.wikipedia.org/wiki/Classical_electromagnetism_and... and https://en.wikipedia.org/wiki/Moving_magnet_and_conductor_problem https://en.wikipedia.org/wiki/Moving_magnet_and_conductor_pr...
- im3w1l 11y agoI think they may use near field rather than radiation for communication.
- angdis 11y agoYes, this is definitely near-field stuff. It can also be done with electric potential!
