So, when the earth's polarity reverses, will all your cupboard doors open?
From the web:
When the
reversed patches grow to the point that they dominate the rest of the core, Earth's overall magnetic field flips. The last
reversal happened 780,000 years ago during the Stone Age, and indeed there's evidence to suggest the planet may be in the early stages of a
pole reversal right now.
