Expanding solar system result in weaker magnetic field.

Thanks for all the reponses to my postings.
I think the concensus is that the solar system is expanding
according to the rest of the universe. In that case the distance
to the sun is incresing resulting in a weaker magnetic field
between the sun and the Earth. I have calculated that the distance
increase 630 meters a year. Does it sound reasonable?
In that case the Earth magnetic field is decreasing 100 ppm a year.
This has impact on the growth of herbs (experiment carried out by me in
April with herbs in pulsating magnetic field) which lead to larger plants.
