I’m mostly curious about what happens. Clearly, it has no significant consequence, or people
It is easy for me to visualize how DC would travel through the knot and the loop. Wunder offered the “it works like an air coil with a single loop” for the RF in the loop itself.
Electromagnetic waves are something for which I have no intuition. When they hit the knot+loop, I have no intuition as to whether they basically ignore it and barrel on through in a straight line despite there being no straight-line conductor, or do they follow the conductor?
