Ada yang tau ga tentang badai magnetik??

Bagaimana kejadiannya??

Penyebabnya apa??

Biasanya periodenya berapa lama??

Terus daerah yang terpengaruh berapa luasnya??

Yang tau kasih tau donk??????
Surga Itu bukan tentang tempat yang indah, Melaikan Tentang Rasa yang sempurna.

Memang ada gaya magnet di luar angkasa

Badai magnetik yang kayak gimana yang dimaksud?
Kalo badai magnetik yang dialami bumi sih ada.
Biasanya terjadi kalo bumi terkena solar wind nya matahari.
Energi dari matahari menyebabkan medan magnet bumi terganggu dan berubah "untuk sementara", makanya disebut badai.
Perubahan medan magnet yang mendadak tersebut menyebabkan partikel bermuatan yang ada di atmosfer meningkat atau berubah arah (misalnya di lapisan ionosfer).
Nah, kalo udah begini, biasanya kejadian magnetis yang sering terjadi di belahan kutub akan terlihat di wilayah lain, misalnya Aurora.
Partikel bermuatan ini juga berbahaya buat penerbangan, karena dapat merusak sistem navigasi, atau menginduksi pesawat menjadi bermuatan.

Periodenya ga lama-lama amat, ya tergantung gangguannya mataharinya
seberapa lama.

Daerah yang terpengaruh juga tergantung seberapa parah badainya.
Supaya bisa dibayangkan, pada tanggal 13 Maret 1989 terjadi badai magnetik dan mempengaruhi berbagai macam peralatan listrik di Quebec. Agustus 1989, badai magnetik merusak mikrochip yang akan dipasarkan di Toronto.

Oya, perubahan fluks magnet yang tiba-tiba ini juga bisa mengacaukan sistem elektronik yang ada di bumi.

Di luar angkasa ada medan magnet ko. biasanya di sekitar benda-benda langit.

Misalnya badai magnetik di Jupiter.

A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a disturbance in the interplanetary medium. A geomagnetic storm is a major component of space weather and provides the input for many other components of space weather. A geomagnetic storm is caused by a solar wind shock wave and/or cloud of magnetic field which interacts with the Earth's magnetic field. The increase in the solar wind pressure initially compresses the magnetosphere and the solar wind magnetic field will interact with the Earth's magnetic field and transfer an increased amount of energy into the magnetosphere. Both interactions cause an increase in movement of plasma through the magnetosphere (driven by increased electric fields inside the magnetosphere) and an increase in electric current in the magnetosphere and ionosphere. During the main phase of a geomagnetic storm, electric current in the magnetosphere create magnetic force which pushes out the boundary between the magnetosphere and the solar wind. The disturbance in the interplanetary medium which drives the geomagnetic storm may be due to a solar coronal mass ejection (CME) or a high speed stream (co-rotating interaction region or CIR)[1] of the solar wind originating from a region of weak magnetic field on the Sun's surface. The frequency of geomagnetic storms increases and decreases with the sunspot cycle. CME driven storms are more common during the maximum of the solar cycle and CIR driven storms are more common during the minimum of the solar cycle.

There are several space weather phenomena which tend to be associated with a geomagnetic storm or are caused by a geomagnetic storm. These include: Solar Energetic Particle (SEP) events, geomagnetically induced currents (GIC), ionospheric disturbances which cause radio and radar scintillation, disruption of navigation by magnetic compass and auroral displays at much lower latitudes than normal. In 1989, a geomagnetic storm energized ground induced currents which disrupted electric power distribution throughout most of Quebec province[2] and caused aurorae as far south as Texas.[3]
