New research expands role of ໂລກ magnetic field. In addition to protecting ແຜ່ນດິນໂລກ from harmful charged particles in incoming solar wind, it also controls how the ພະລັງງານ generated (by charged particles in solar winds) is distributed between two the poles. There is northern preference meaning more energy is diverted to magnetic north pole than magnetic south pole.
ແຜ່ນດິນໂລກ’s magnetic field, formed due to flow of superheated liquid iron in the outer core of ແຜ່ນດິນໂລກ below 3000 km from the surface plays very important role in our life. It deflects the stream of charged particles emanating from the Sun away from the ແຜ່ນດິນໂລກ thus shielding life from the harmful effects of ionising ລົມແສງຕາເວັນ.
When the electrically charged particles in the solar wind flows in the atmosphere, they generate energy. This terrestrial electromagnetic energy is hitherto understood to be symmetrically distributed between north and south poles. However, new research using the data from the Swarm satellite in polar low-ແຜ່ນດິນໂລກ orbit (LEO) at an altitude of around 450 km, has shown that this is not the case. The energy is preferentially distributed to the north pole. This asymmetry of northern preference means more of terrestrial electromagnetic energy heads towards magnetic north pole than towards magnetic south pole.
ສະ ໜາມ ແມ່ເຫຼັກຂອງໂລກ ດັ່ງນັ້ນ, ຍັງມີບົດບາດໃນການແຜ່ກະຈາຍແລະຊ່ອງທາງຂອງພະລັງງານແມ່ເຫຼັກໄຟຟ້າເທິງແຜ່ນດິນໂລກ (ເກີດມາຈາກການເຂົ້າມາຂອງອະນຸພາກທີ່ມີຄ່າໄຟຟ້າ) ໃນບັນຍາກາດ.
ລັງສີ ionizing ໃນ ແສງຕາເວັນ ລົມແມ່ນເປັນທີ່ຮູ້ກັນວ່າມີທ່າແຮງທີ່ຈະສ້າງຄວາມເສຍຫາຍຕໍ່ເຄືອຂ່າຍສື່ສານ, ລະບົບນຳທາງທີ່ໃຊ້ດາວທຽມ ແລະ ຕາຂ່າຍໄຟຟ້າ. ຄວາມເຂົ້າໃຈດີຂຶ້ນຂອງ ຂອງໂລກ ສະໜາມແມ່ເຫຼັກຈະເປັນປະໂຫຍດໃນການວາງແຜນຄວາມປອດໄພ ແລະປ້ອງກັນລົມແສງຕາເວັນ.
