Yes, exactly like something pushed out a circular shock wave.
Yup. Folks can see the same effect if they watch the aerial footage of the atomic bomb tests in the Pacific - that same sort of shock wave moves out from the explosion center along the surface of the ocean in that footage.
I suppose magnetism might work the same way if given a surface laden with magnetic material and a moving magnet getting closer to it or farther away. The phenomena behaves like an invisible sphere, either getting closer to the surface (think of how successive "slices" of the sphere would get larger and larger until they reached it's maximum diameter) or, as in the case of an explosion, expanding outward from the center as it pushes along.
In the case of an explosion, it would also get weaker as it gets larger until it disappears - the same energy is being spread out over a larger radius, so there would be a "weakening" as the energy expanded, less pounds per square inch because the square inches are increasing but the energy expanding doesn't. Instead, it "thins out" following the law of inverse squares.
