WHICH ONE???
‘-’ sign indicates direction of
induced EMF and N no. of turns
including the change of flux with
respect to time
EMF equals rate of change of flux*
In this position (of conductor)
velocity of conductor is
parallel to the
lines of
magnetic field  no cutting of
flux. So change of flux is
minimum and no induced
EMF.
In this position (of conductor)
velocity of conductor is
perpendicular to the lines of
magnetic force  max cutting
of flux. So change of flux is
maximum and max induced
EMF occur in this position.
Again in this position velocity of
conductor is parallel to the lines of
magnetic field  no cutting of flux.
So change of flux is minimum and no
induced EMF when conductor is
aligned horizontally again.
Further Shifting
-Induced EMF get reversed
-Opposite position of the conductor
Remaining o/p when shifted again with parallel
velocity of conductor respect to the lines of
magnetic force Complete Sinusoidal waveform
produced in the generator.
So conductor keeps on rotating and o/p voltage
keeps on inducing…
Rotator keeps rotating but o/p voltage is
always in one direction

Enameled wire is a copper or
aluminum wire coated with a
very thin layer of insulation.
Number of paths for current between the terminals of the machine

Drop forging is a process that uses a pair of impression dies and
a heavy hammer to form and compress metal bars or billets
into complex shapes.
Hard-drawn copper is bare copper wire that hasn't had heat
applied to it after it has completed the drawing process through
the dies.
