Jupiter's
Magnetic Field/Magnetosphere
-
Generated
by circulating charges in liquid metallic hydrogen core
-
analogy
to circulating charges in Earth's liquid iron core
-
Jupiter's
field is more than 10 times stronger than Earth's
-
Jupiter's
magnetic field tilted 11 degrees with respect to Jupiter's rotation axis,
rotates slower than atmosphere
-
Equatorial:
9h 50m
-
Magnetic
field: 9h 55m
-
Carves
out magnetosphere in solar wind
-
Recall
Earth's magnetosphere caused Aurora Borealis (Northern lights)
-
Charge
stored in van Allen Belts
-
Jupiter
has Aurora as well
-
Jupiter's
stored charges flung out by fast rotation into a current sheet
-
Visible
at radio wavelengths
-
electrons
spiral around magnetic field lines
-
oscillating
charges send out radio waves
