Voorbeelden van field lines

• The field lines of the background fields lie on constant -planes; the relations (35)- (38) allow a great variety for their shapes.

• It reduces the two-dimensional to a one-dimensional problem, leaving only derivatives along the field lines.

• In the core of the flow the leading-order dependence of all fluid variables along the magnetic field lines can be described analytically for many problems.

• This vorticity is clearly such as to inhibit motion of the fluid across the magnetic field lines (see figure 5).

• The axial magnetic field lines are thus compressed and will conserve their flux throughout the implosion.

• In this paper, we have explored, on the basis of laboratory experiments, the creation of a flux tube with twisted magnetic field lines.

• Knowing this one finds immediately that the inertial correction to the electric potential has a parabolic behaviour along magnetic field lines.

• The plasma pressed by the magnetic field to the internal electrode is unstable because of an unfavorable curvature of the magnetic field lines.

• Because the magnetic field lines resist "bending," such azimuthal asymmetries are not expected to grow and become unstable.

• In a magnetized plasma, we have a natural symmetry axis along the direction of the magnetic field lines.

• The poloidally closed grid lines again coincide with magnetic field lines.

• The magnetic field lines, however, are no longer plane.

• The other class comprises equilibria with straight magnetic axis and field lines lying in planes orthogonal to the axis.

• Figure 9 shows the magnetic field lines at the six instants.

• This approach is formally equivalent to the determination of magnetic field lines, which satisfy the same mathematical equations.
