The Sun has a Magnetic field which apparently extends to the outer limits of the Solar System. As the Sun rotates, this field must rotate with it. The magnetic field may appear to spiral because of propagation delay, and this seems to be in agreement with the following.
At great distances, the rotation of the Sun twists the magnetic field and the current sheet into the Archimedean spiral like structure called the Parker spiral. https://en.wikipedia.org/wiki/Sun
This spiraling, if it does exist, would be an effect of the "Solar Wind" travelling at a relatively slow speed of about 400 KPS. The Dynamic Gravitational Field I describe in these pages would be a quite distinctly different instantaneous entity.
I have seldom seen anything describing the rate that this magnetic field must sweep the planet's magnetic fields. We are told about the "Solar Wind", but this is always described in a very static way. The Sun's magnetic field may be both compressing and sweeping the Earth's magnetic field at a velocity that is about 12 times the speed that the Earth is orbiting the Sun. My calculations show this sweeping velocity to be a bit more than 1.1 million Klm per hour after allowing for 107,000 klm per hour orbital speed.
