The
two basic magnetic-fields effects result in the production of forces.You are asked to investigate the main
parameters which affect these results; You should cover the alignment of flux
lines interaction between magnetic fields and finally conductors which carries
the electric current.The main factor here is the forces are the main
product and they are mechanical and operating on mathematical bodies that have
no overall electric charge as they are ultimately of electric origin. The
investigation should cover mainly the electromechanically energy conversion and
its main parameters.You also asked to select any of the machines
to discuss in more detail the main factors and aspects of design for a
Transformer as a static machine or any motor or generator.
