    As Sunspots have got high magnetic field what is the effect of magnetic field on the earth?

    If you are asking how the Sun's magnetic fields affect the Earth - they are the causes of solar activity, which can affect out technologies (power systems, spacecraft, communications) in various ways and also cause the Northern and Southern lights.

    See for more information.

    A lot of how the Sun's magnetic field affects us is tied into Earth's magnetic field. Earth's magnetic field protects us from some of the effects of solar activity. We also use Earth's magnetic field for navigation. Other "terrestrial" planets (Mercury, Venus, and Mars) have smaller magnetic fields than Earth. this may have affected their evolution. That is one of the things the MAVEN mission to Mars is studying

    Sometimes the really strong magnetic fields cause extra radio "noise"...this is mostly just interesting unless you're a ham radio operator!
