static induced emf when the voltage source across the prim
coil is alternating "AC" then the flux rotate making flux
dynamic emf is when the voltage source across the primary
coil is direct current "DC" so u must rotate the secondary
coil to make flux linkage or rotate the primary coil ..two
r the same.
Meaning of a static is stationary. so there is no relative
motion between field nor coil. The source should be
alternating in nature. Then only emf can be induced.
In dynamically induced emf there is relative motion
between conductor and field. Because relative speed is an
important point to get the dynamically induced emf.
In statically induced emf, conductor is stationary with
respect to the magnetic field.Transformer is an example of
statically induced emf. Here the windings are
stationary,magnetic field is moving around the conductor and
produces the emf.
Generator is an example of dynamically induced emf.
firstly,dynamic means movement...secondly,to get induced
EMF, the magnetic field and the coil have to be established
in an arrangement.
dynamic EMF is induced in a moving coil due to the
constant field(produced by DC current) produced by the
stationary (no physical moving)coil or vice versa.
static means no phyiscal moving so static EMF is induced in
a stationary coil due to the change the field in nature
(supplied ac current) in the another stationary coil so
Those emf which is statically produced one to other coil by
transfer of static magnetic flux is known as static induced EMF
but dynamically induced emf are Stationary windings magnetic
field is moving around the conductor and produces the emf.
& that happens in generator for production of dynamic
Dynamic EMF- When there is motion of conductor in magnetic
field then emf is induced which is called as dynamically
induced emf or simply dynamic emf.
Static EMF- when conductor is kept stationary in magnetic
field then the emf induced is called statically induced emf
or simply static emf.
