  Non-solitonic examples of the application of geometrical and topological
methods in plasma physics and magnetohydrodynamics (MHD) are given. The first
example considers the generalization of magnetic helicity to gravitational
torsion loop. The second example considers also the application of this same
torsion loop metric to some problems of helical fields in MHD dynamo theory. In
the last example a Riemannian magnetic metric is given where the magnetic field
itself is present in the diagonal time-independent metric. In this example the
MHD equations are shown to be compatible to the geometrical Bianchi identity by
making use of Cartan's differential calculus formalism. The Riemann curvature
of the helical flow is also obtained.
