I saw that episode of NOVA too. There is ample evidence that the field has reversed polarity many times in the past, so it is reasonable to assume it will do so again in the future. It may drop to zero, or nearly zero, temporarily while it changes polarity, and that temporary time period may be many years or even centuries, but it will not permanently disappear. Of course, if it stays near zero for 500 years, that is essentially permanent from the point of view of a person who lives only 100 years.
And in case you are worried about the consequences, there may be some, but not as severe as you might suspect. The polar regions are always unprotected anyway because of the shape of the field.

Magnetic storms strike Earth continuously. We had 2 huge ones hit almost a month in the past. They reason colourful Auroral reflects, and disrupt some cellphones the following or there. yet there is genuinely no genuine way for everyone to wisely predict a significant image voltaic magnetic typhoon to strike in 2013, or next month, or ever. The solar is continually churning, and magnetic storms do ensue each and every so typically. yet our digital technologies is nicely developed adequate that our banking pcs might want to live to inform the tale something short of a monster, huge, cataclysmic CME thrown instantly into our faces. If that would want to take position, then economic corporation pcs may be the most trivial of our concerns. once you're searching at a Mass Extinction adventure, you do not stop to stability your checkbook.

Evidence has demonstrated that the Earth's magnetic field is decaying, which provides evidence for a young earth. This magnetic force is also responsible for holding a magnetosphere layer of charged particles called the Van Allen belts, which protect the Earth from cosmic bombardments.
Those who hold the Earth to be billions of years old must believe that this current is generated by some ongoing process (i.e. the growth of the core, convection, etc). Most evolutionists hold to the magnetic-dynamo model of Earth's magnetic field
The Earth's magnetic field and the Van Allen belts protect us from most of the stream of charged plasma called the solar wind, which is constantly emitted by the sun. Cosmic rays from space and from the sun are made of highly energetic charged particles. These particles can be very dangerous to life

Not unless the molten core of the earth disappears - which it isn't likely to do!

no, when the poles move, they do so gradually, fading in one spot and appearing in another.
