The researchers implanted arrays of magnetic palladium - cobalt dots on a superconducting film of lead, lining up the dots»
magnetic poles so they all pointed the same way, explains team leader and physicist Victor Moshchalkov.

So if you're standing over the north
magnetic pole with a compass, the needle would dip and try to point straight down — hence its other name: the
magnetic dip
pole.
So the north
magnetic pole is where the earth's
magnetic field lines pull toward the planet, acting like the south
pole of a bar magnet.
The star's
magnetic poles switch places every 11 years or
so.
The neutron star's
magnetic field lines converge at the
magnetic poles,
so the charges get focussed and a narrow cone of non-thermal radiation is beamed outward.
The polarity of the leading sunspot alternates every solar cycle,
so that it will be a north
magnetic pole in one solar cycle and a south
magnetic pole in the next.
Not only does the Earths
magnetic field wander around on time scales of a century or
so, but every 100,000 years or
so it completely changes direction, with the north (
magnetic)
pole becoming the south (
magnetic)
pole.
