The earth's magnetic field deflects the flow of current from:
a) the moon
b) saturn
c) the sun
d) the center of the earth

C) the sun

Explanation:

Due to nuclear reaction on the surface of sun there is high temperature on the surface of sun also due to nuclear fusion of hydrogen atoms there is large number of high energy charge particles released out.

This high energy charge particles are known as solar flares which moves towards earth at high speed.

Now when these charge particles enters into the magnetic field of earth then it gets deviated due to earth magnetic field

the force on the charge is given by

so here the correct answer would be

C) the sun
