See below for details. Just imagine if the earth's magnetic field
Where is the north end of a magnet. and where is the Earth's north pole?
Do we have to change the right hand rule to the left hand rule?
Do we have to remark each little magnet we own to rename the north and
Does the electron charge become positive?
IF so, what is the charge on a positron?
Which way does current flow?
The confusion could become huge. Do we set up giant currents in giant
coils to try to keep our existing magnetic field polarity?
Do we outlaw electric current as we may deduce our electicity is causing
Here is the article reporting an article that portends such a possibility.
**NYT: COLLAPSE OF THE EARTH'S MAGNETIC FIELD ACCELERATES

The collapse of the earth's magnetic field, which both guards the planet
and guides many of its creatures, appears to have started in earnest
about 150 years ago, the NY TIMES is planning to report on Page Ones
Science reporter Bill Broad has filed a report, according to newsroom
sources, which explores how: 'The field's strength has waned 10 percent
to 15 percent so far and this deterioration has accelerated of late,
increasing debate over whether it portends a reversal of the lines of
magnetic force that normally envelop the earth."
Broad explains: "During a reversal, the main field weakens, almost
vanishes, and then reappears with opposite polarity. Afterward, compass
needles that normally point north would point south, and during the
thousands of years of transition much in the heavens and Earth would go
Broad claims: "A reversal could knock out power grids, hurt astronauts
and satellites, widen atmospheric ozone holes, send polar auroras
flashing to the equator and confuse birds, fish and migratory animals
that rely on the steadiness of the magnetic field as a navigation aid."
