The magnetic strength of the field magnet influences greatly the speed of the armature; the stronger the field magnet the greater the motion, so electricians make every effort to strengthen their field magnets.

From General Science by Clark, Bertha M.

The object of the field magnet is to produce an intense magnetic field within which the armature revolves.
