1t has been calculated, according to
Prof. Schuster, that if the sun were
made Of the hardest steel and thorough
y magnetized the distance between it
and the earth is so great that 1t could
not affect our magnets. The connec
ton between the sun and the earth,
whereby magnetic storms occur on our
planet Immediately after the appear
ance Of sun-spots, is therefore one of
the greatest scientific mysteries of this
age. Thus far the efforts Of physicists
have utterly failed to account for such
phenomena.
