STATICALLY INDUCED EMF

The emf induced in a coil due to change of flux linked with
it (change of flux is by the increase or decrease in
current) is called statically induced emf.

Transformer is an example of statically induced emf. Here
the windings are stationary,magnetic field is moving around
the conductor and produces the emf.

DYNAMICALLY INDUCED EMF

The emf induced in a coil due to relative motion of the
conductor and the magnetic field is called dynamically
induced emf.

example:dc generator works on the principle of dynamically
induced emf in the conductors which are housed in a
revolving armature lying within magnetic fie

Answer / shruti

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.

Answer / arb555

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.

Answer / moody

static induced emf when the voltage source across the prim
coil is alternating "AC" then the flux rotate making flux
linkage!
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.

Answer / gaurav

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.

Answer / guest

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

Answer / ramesh

Those emf which is statically produced one to other coil by
transfer of static magnetic flux is known as static induced EMF
Ex- transformer
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
induced emf

Answer / ramanjaneya reddy

dynamicall induced emf:-
the emf induced in a conductor due to its motion in a uniform magnetic field is known as dynamically induced emf.according to faraday's second law of electro magnetic induction when a conductor cuts the magnetic flux, dynamically induced emf is produced

Answer / santosh kumar. yadav

If coil or conductor is constant flux is rotating static if flux is constant coil or conductor is rotating it is dynamic. 

Answer / pramod

The emf induced in a conductor due to reactive motion but were magnetic field and conductor is called dynamically induced emf

2 Answers   BARC,

Dear all, I just want to ask an expert on this forum for some insights. For the magnetic balance test, when applied voltage on a Delta-Star transformer e.g. Dyn11, the following relationships apply for HV side: 1.  H1-H2 = H2-H3 H3-H1 2.  H2-H3 = H3-H1 H1-H2 3.  H3-H1 = H1-H2 H2-H3 For the LV side also: 4.  X1-X0 = X2-X0 X3-X0 5.  X2-X0 = X3-X0 X1-X0 6.  X3-X0 = X1-X0 X2-X0 Is there a similar pattern for Y-d, Y-Y, D-d? And how about Y-z, D-z, Z-y transformers? I've tested a YNzn5 transformer and for LV side I don't see the pattern. In this particular case I got for LV side the following (see values below): H1-H0  H2-H0  H3-H0    X0-X1  X0-X2  X0-X3 128.0  119.9  7.2      29.2   13.3   15.8 70.7   128.4  59.2     23.4   22.0   3.6 7.2    120.1  128.1    13.4   29.3   15.8 What is the relationship here for LV? For row 1 I see the relationship, for row 3 I also see but it's shifted, but for row 2 I don't see such relationship. Any suggestions, answers, someone?
