The poles don't just flip. There are many anomalous magnetic areas
around the world.
"Reversals take a few thousand years to complete, and during that
time--contrary to popular belief--the magnetic field does not vanish.
"It just gets more complicated," says Glatzmaier. Magnetic lines of
force near Earth's surface become twisted and tangled, and magnetic
poles pop up in unaccustomed places. A south magnetic pole might emerge
over Africa, for instance, or a north pole over Tahiti. Weird. But it's
still a planetary magnetic field, and it still protects us from space
radiation and solar storms." A quote from,

Some day the magnetic pole will flip to the south pole. This will really
change the declination numbers!

## are u sure the declination has changed 10 degs in just 20 years ? I
find
that
hard to believe. Its 30 degs for us folks in VE7 land. Same as it always
has been.
Declination is changing each year, but a miniscule tiny amount. Interesting
to note that
we also point 30 degs for down town EU.... so magnetic north and EU are one
and the
same.
