It my understanding that it takes two fields to propagate through space, electric and magnetic, but what about a magnetic field created when a solenoid is energized with direct current? How exactly does that magnetic field travel? There is no frequency involved with direct current. What determines the extent of the magnetic field before it collapses? Finally, what about permanent magnets. How do they propagate? There is no frequency here either. To summarize my questions: How do magnetic fields get from point A to point B without a frequency and collapsing fields? Thanks
