They technically can and that is what Apple was trying to do but the overlap creates a lot of weird RF noise and makes stable induction difficult.

Yes, it's just a much harder physics problem.
- Tempest1981 8y agoIf you send power to one coil, some % will be induced in adjacent coils, right? And I guess that radiates interference like an antenna? So question: could an inverse signal be applied to adjacent coils to cancel out the interference (from induction)?
- kickopotomus 8y agoI believe that is what Apple was trying to do, but again, it is a very hard, non-linear problem. By attempting to counteract that noise, you get a bunch of competing, variable magnetic fields.
