Answer:
The rotation of the Earth causes the buoyant fluid to rise in curved trajectories, which generate new magnetic field by twisting and shearing the existing magnetic field. ... Occasionally, however, the dipole part of the field reverses, causing the locations of the north and south magnetic poles to switch.21 Oct 1999
