Magnetic Poles
Planetary magnetic poles are defined analogously to the Earth's North and South magnetic poles: they are the locations on the planet's surface at which the planet's magnetic field lines are vertical. The direction of the field determines whether the pole is a magnetic north or south pole, exactly as on Earth. The Earth's magnetic axis is approximately aligned with its rotational axis, meaning that the magnetic poles are relatively close to the geographic poles. However, this is not necessarily the case for other planets; the magnetic axis of Uranus, for example, is inclined by as much as 60°.

Famous quotes containing the words magnetic and/or poles:
“We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.”
—Henry David Thoreau (1817–1862)
“I see you boys of summer in your ruin.
Man in his maggot’s barren.
And boys are full and foreign in the pouch.
I am the man your father was.
We are the sons of flint and pitch.
O see the poles are kissing as they cross.”
—Dylan Thomas (1914–1953)
