Agreed, static magnetic fields tend to decay rapidly as you move away
from them. However, alternating magnetic fields continue to propogate
by generating alternating electric fields of the same frequency. These
alternating electric fields, in turn, generate alternating magnetic
fields. The cycle keeps repeating.

Nonsense as stated.

No, it's just a qualitative restatement of Maxwell's theorems.
Changing e-field makes H-field, changing H-field makes e-field, and
they toodle off into the sunset at the speed of light.
