Solar Wind

Solar Wind is charged plasma ejected from the sun at 400km/s to 750km/s and even as fast as 1000km/s during Solar Flares. It has a 27 day cycle and even can decrease 98% at sparse happenings. It carries a magnetic field with it. It is strong enough to interact with the planets and their magnetic fields to shape magnetospheres, earth's effect from this plasma. The magnetosphere is shaped like a sphere in the upper atmosphere around where the atmosphere faces the sun and has a tail away from the earth.
The solar wind blasts the planet at supersonic speeds producing a bow shock. The sun also has a magnetosphere from the intersteller winds.

My question is can someone estimate the varying magnitude of the magnetic field associated with the Solar Wind.
