desc.magnetic_fields.ToroidalMagneticField

class desc.magnetic_fields.ToroidalMagneticField(B0, R0)Source

Magnetic field purely in the toroidal (phi) direction.

Magnitude is B0*R0/R where R0 is the major radius of the axis and B0 is the field strength on axis

Parameters:

  • B0 (float) – field strength on axis

  • R0 (major radius of axis) –

Methods
