TGeoGlobalMagField Class Reference

Global magnetic field manager.

Provides access to and owns the actual magnetic field set via SetField(). The field is deleted upon destruction of the field manager at the end of ROOT session or by calling:

The previous global field is deleted upon replacement with notification.

The global field manager provides access to the global field via:

One can directly call the Field() method of a field via the global field manager:
