Unraveling the Mystery of Magnetosphere: How Does it Occur?

[aditya23456]

how does this phenomenon occur.?this a case of magnetosphere..I don't understand how this happens.

 

[mfb]

Charged particles moving in a magnetic field experience a force perpendicular to their direction of motion.

What do you mean with "deflect away from a source"?

 

[aditya23456]

i read that solar particles deflect away from entering Earth due to its magnetic field..I know a charged particle circulates in a field or in this case it should deflect back towards sun after taking a semi circle..is this the case.?

No, they don't necessarily go back to where they came from. Just some other direction.

A lot of the charged solar particles actually get trapped by and in the Earths magnetic field and spiral down the field lines to the north and south polar regions. This is why we get aurora
And a lot more will stream around the magnetic field and down the very extended tail of the field

do some google searching on " the bow shock of the Earth's magnetic field" and variations of that

Fast charged particles that enter the Earth's magnetic field will tend to follow a spiral path which may collide with the planet's surface. This path is longer than the direct path and they are slowed down more on the way in, losing their (dangerously ionising level of) energy before they can hit the biosphere.
