Link to The universe (T5): Magnetic storm documentary
Documentary Description
It bursts from the sun with the power of ten thousand nuclear weapons...
and when it hits our planet, it could create the largest disaster in
recorded history. A magnetic storm from the sun could wipe out
electrical power, television, radio, military communication, and nearly
every piece of electronics in the Northern Hemisphere. It's a "Solar
Katrina" -- a planet-wide "hurricane" of magnetic forces that scramble
all 21st Century technology, possibly for good. What causes this
magnetic superstorm? Why is magnetism so powerful -- and yet so poorly
understood? And is there anything we can do to prevent the Magnetic
Storm?
