Detailed Description

The magnetic field parameters.

The class defines the type of equation of motion of a particle in a field and the integration method, as well as other accuracy parameters.

The default values correspond to the defaults set in Geant4 (taken from Geant4 9.3 release.) As Geant4 classes to not provide access methods for these defaults, the defaults have to be checked with each new Geant4 release.
