magnetic field. as in the case of the
armature Of generator, the presence
Of the field has been assumed and
nothing has been said as to the method
OF providing the magnetic field. The
term field" he applied interchange.
ably TO the magnetic lines OF force be-
tween the pole faces OF the field mag.
nets and to the field magnets them.
selves. There are two methods OF
producing the magnetic field for gen.
orators and motors. and these methods
will be discussed in the following para.
graphs:
The permanent magnet provides per.
haps the simplest method Of producing
a magnetic field. The field produced
by permanent magnet Is quite weak
as compared to one produced by an
electric current, and the magnetic field
OF the permanent magnet cannot read
lily be changed 10 meet changing re.
quirements. The use OF the permanent
magnet as means OF producing a
magnetic field Is confined In motor
cars almost entirely to the ignition
magnetic at the present time.
