Detailed Description

The cached magnetic field defined by the TVirtualMCApplication field map.

Overrides TG4MagneticField::GetFieldValue(); it uses the value from a previous call in case the distance of the new point from a previous one is smaller than the value of TG4FieldParameters::fConstDistance.

According to G4CachedMagneticField class.
