MAGNETOSPHERE PRESENT UNTILL FUTURE

The importance of the Earth's magnetic field for live has discovered in this century. These data from measurement in earth surface and satellite have been supplemented with less precise data based on inferred values of the magnetic field deduced from remnant magnetic fields in rocks, pottery, and similar objects that can become magnetized as they cool. We are sure changing the magnetic field in future is cause of lowering its strength and this subject is an alert for our life on the Earth so finding a suitable way to face this problem is so necessary.
