Detailed Description

Definition of a uniform magnetic field.

This class demonstrates definition of a user magnetic field via the TVirtualMagField interface. In case of a uniform magnetic field, it is also possible to use directly the TGeoUniformMagField class in the VMC application.

x	The position
B	he field value (in kiloGauss)
