Non-uniform magnetic-field spatially and temporal pulsed magnetic field pass through this non-uniform magnetic-field spatially and temporal pulse
Magnetic field causes to be formed the effect of surge, for spatially, specifically by a non-uniform driving force inside metal liquid
Process is such, by permanent magnetism partition board in for fan-shaped, it is assumed that when original state the South Pole of permanent magnetism partition board downward, arctic court
On, the South Pole rotation of permanent magnetic stirring magnet at this time comes, since the magnetic field intensity of permanent magnetic stirring magnet is more than the magnetic of permanent magnetism partition board
Field intensity, permanent magnetism partition board are magnetized, and become the arctic downward, the South Pole upward, due to obtaining the reinforcement in permanent magnetism partition board magnetic field, permanent magnetism
Metal liquid right over partition board is under the field drives of a bigger, and the metal fluid rotated at this time is in the position of permanent magnetism partition board
It sets（The South Pole of permanent magnetic stirring magnet is located just at the underface of permanent magnetism partition board at this time）, arctic relative to permanent magnetic stirring magnet
Position, by the field drives of bigger, this uneven driving may result in the deformation and compression of metal fluid, in metal fluid
