Creative nonfiction writer Susan Schorn delivers a craft talk on «
Finding Magnetic North: Revising and Shaping Your Creative Nonfiction.»
«Early navigators used it to
find the magnetic North Pole and birds use it for their navigation.

Monarchs, they
found, navigate
north or south using the change in dip of Earth's
magnetic field lines with latitude.
To
find out how the turtles remain within the gyre, Ken Lohmann of the University of
North Carolina at Chapel Hill and colleagues made hatchlings swim in the presence of
magnetic fields that simulated locations off Portugal, by which the gyre passes.
Earlier work by Kenneth Lohmann of the University of
North Carolina (UNC), Chapel Hill, and his colleagues had
found that eastern Florida's loggerhead sea turtles sense
magnetic fields.
Here we report that hatchling loggerheads, when exposed to
magnetic fields replicating those
found in three widely separated oceanic regions, responded by swimming in directions that would, in each case, help keep turtles within the currents of the
North Atlantic gyre and facilitate movement along the migratory pathway.
Earth has its own
magnetic field, which is why we can always use a compass to
find the
north pole no matter where we are.
Hidden in a niche between rugged, tree - topped hills is Nelly Bay, a small port town
found on
Magnetic Island just a few miles
north from the coast of Queensland, Australia.
