Hello everybody, First excuse me for my English.

Could someone please explain how far the electromagnetic wave of a coil travels?
Does it depend on the current flowing in the coil? The coil diameter? The coil's number of turns?
What will happen to the waves if we increase the current of a coil by two times?

Thanks in advance,
SMT

According to classical theory it spreads without limit but weakens with distance.Try googling Biot and Savarts law.
