... and toroidal fields. Velocity shear (differential rotation) naturally generates toroidal from poloidal field. The α-effect of mean field electrodynamics can complete the cycle and regenerate poloidal from toroidal field. With a judicial choice of α and β (and differential rotation ω) it is possible ...

Adding up all those pushes, or motions, creates the nice spinning movement of a motor. There are actually several ways to make the ...
