And if you can bring another device close enough to the source, that will only work at exactly that frequency, you can actually get them to do what's called strongly couple, and transfer magnetic energy between them.
Si daca puteti aduce un alt dispozitiv suficient de aproape de sursa, acesta va functiona exact la aceeasi frecventa, le veti putea face sa lucreze precum un cuplu, si sa transfere energie magnetica intre ele.
