# Magnetic flux tube

In this section:

Alfvén Mode ( n=0 )

Alfvén Mode ( n=1 )

Sausage Mode ( n=0 )

Kink Mode ( n=1 )

Fluting Mode 1 ( n=2 )

Fluting Mode 2 ( n=3 )

Fluting Mode 3 ( n=4 )

Fluting Mode 4 ( n=5 )

Fluting Mode 5 ( n=6 )

The 3-dimensional standing mode solutions of the linearized MHD equations in a cylindrical geometry for sausage, kink and fluting modes for upto n=6, can be seen to the right. The visualizations are based on the solutions obtained by Edwin and Roberts (1983).

Here, n is the azimuthal wave number. For all cases the following parameters are used:

The parameters in a magnetic flux tube waveguide are defined as:
