Sentences with phrase «magnetic north becomes»

Not exact matches

For example, scientists don't understand why the magnetic field is as strong as it is, or why the field reverses polarity — the North Pole becomes the South Pole and vice versa — every several hundreds of thousands of years, briefly vanishing in between.

A geomagnetic reversal is a change in the orientation of Earth's magnetic field such that the positions of magnetic north and magnetic south become interchanged.

However, preliminary research suggests there are at least three problems concerning metal in beds: 1) metal can concentrate and radiate a variety of EMR from other sources (the EMFs that have been studied extensively), 2) metal can become permanently magnetized, and 3) metal disrupts our orientation to magnetic north.

Not only does the Earths magnetic field wander around on time scales of a century or so, but every 100,000 years or so it completely changes direction, with the north (magnetic) pole becoming the south (magnetic) pole.

- Where the North magnetic pole was being «pushed on» becomes «pulled on» - Where the South magnetic pole was being «pulled on», becomes «pushed on» The Earth's magnetic and gravitational field around the equator changes very much seasonally, due to constant rotation and equally distributed exposure to the Sun's E / M field.
