one challenge needs to be addressed before the wires can be considered for popular products: how to minimize leakage of the metal if the wires are severed.
Nope, it wouldn't. Why the deform of metal should lead into electromagnetic field? Not quite accidentally, you were upvoted for it with three people already.(wish I could flag you for bad English)
Because the PO is increasingly flooded with naive kids, who A) don't understand physics and B) who expect huge exploitation of every silly result of basic research regardless its actual price. Just such silly publics enables the lazy incompetent scientists to survive.
Simply waving a piece of metal about doesn't induce anything
But if you're now thinking of using the Earth's magnetic field...
