A geophysical aspect of a disturbed fluid motion in the earth's core
- 16 Downloads
A magnetic dipole is supposed to be suddenly introduced in the earth's core (taken as an inviscid, incompressible fluid of finite electrical conductivity) to act as a source of disturbance. It is shown that although in the symmetric case of the problem the disturbed fluid is stagnant in any direction at the interface separating core from the solid insulating mantle; yet it should slip in any tangential direction at the interface, in each of the three unsymmetric cases considered here.
