Exempel på magneto

• Rotating fluids, cavitation, and, most surprising of all, magneto-hydrodynamics, are also overlooked (or is the latter topic to be treated in another volume?).

• The inclusion of many minor topics such as bore-hole gravimetry, seepage sampling and magneto-tellurics add to completeness.

• The basis for the numerical simulation is a mathematical model that describes the dynamic behaviour of magneto-mechanical sensors and actuators.

• On the basis of both examples the applicability of the presented simulationtechnique to real-life magneto-mechanical problems was demonstrated.

• These equations have a 'magneto-hydraulic ' character, for in the shallow liquid layer the horizontal fluid velocity and current density are independent of the vertical co-ordinate.

• There are several models under development including fetal magneto-cardiography and this may form an integral part of evaluation in the future.

• The unstable mode can be identified as the slow magneto-acoustic mode.

• They have added significance when their similarity to magneto-fluid dynamic and stratified fluid flows is considered.

• This happens especially in the case of large excitations, as they occur, for example, in magneto-mechanical actuators.

• Updated discussions are given of biostratigraphy, graphic cor relation, geophysical log stratigraphy, cycles, and of climate, event and magneto-stratigraphy.

• These stresses remain in phase with the classical (no magnetic field) surface pressures, and no drag results from the magneto-aerodynamic interaction.

• Therefore, the technique was tested and verified by modelling and measuring of two challenging magneto-mechanical devices.

• Magneto-hydrodynamics consists of combining the momentum and conservation equations for the charges in plasma.

• The traditional approach is to apply the mass, momentum, and energy conservation within the magneto-hydrodynamical (single fluid) approximation, adopting phenomenologically a kind of state equation (usually polytropic).

• Magneto systems gave way to common battery systems, and metallic circuits replaced single wire.
