Basic coil

Shape and dimension

The basic coils provided by the Flux library are presented below.

Circular coil Rectangular coil

Current direction

A coil is defined in a proper coordinate system. The direction of the current is dependent on the orientation of this coordinate system and the arrow on the image of the coil defines the direction of the positive current in the coil.

In the basic coil the direction of the current is anti-clockwise oriented around an axis parallel to the OZ-axis.

Sections

The types of associated sections are presented in the table below.
