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 field
What else can I help you with?
The direction of statically induced emf can be found by which law?
Lenz's Law
Difference between induced emf and generated emf?
In an analogy, Generated EMFs can be considered as the speed or force at which the boat is moving, while Induced EMFs can be considered as a standyby boat with no engine, when the moving boat with an engine passes. Generated EMFs, considered as the boat with an engine, is the voltage which is generated by a source, by which in this case is the engine, while the Induced EMF, considered as the boat with no engine, is affected by the moving boat with an engine, thereby also moving the Induced EMF. In a sense, Generated EMFs have their own source while Induced are only 'moved' by other external forces. Like wise when electrons flow on a wire the ripples or magnetic flux will induce or generate motion on any wire or conductor next to it. That's how transformers work.
Which law gives the direction of induced current?
LENZ LAW gives the direction of induced current.
What are the reasons why a current is induced in a coil?
Current is not induced into a coil. It's voltage that is induced into a coil. If the coil is connected to a load, or even short circuited, then a current will flow as a result of the induced voltage -but it's the voltage, not the resulting current, that's induced!Voltage is induced into a coil because the the changing magnetic field, due to the change in current (0 to Imax or vice versa) applied to that coil. The process is called 'self induction'.
How is the induced voltage of separately excited dc generator affected if the speed increases?
as speed increases, induced voltage increases
In colomn answer of difference between statically indused emf and dynamicaly indused emf?
Statically induced emf is produced by the relative motion between a conductor and a magnetic field, while dynamically induced emf is generated due to a change in the magnetic field strength experienced by a conductor. Statically induced emf does not require any physical movement of the conductor, while dynamically induced emf is produced when the magnetic field changes over time.
What is other name of statically induced emf?
Electromagnetic induction
The direction of statically induced emf can be found by which law?
Lenz's Law
What happens to the force exerted between charged and uncharged objects as the distance increases between them?
As the distance is increased, statically induced charge in the uncharged object is reduced to a minimum. Thus coulombic force which is directly proportional to the product of the charges tends to 0
Induced angle of attack in simple terms?
it is the difference between local flow direction and free stream direction of atmospheric air
What happens when metal rod moves in magnetic field?
Induced voltage generates in rod.Voltage difference evolve between two ends.
What is difference between induced voltage and induced current?
Just as a current flowing through a wire will produce a magnetic field, so a wire moving through a magnetic field will have a current flowing through it. This is called electromagnetic induction and the current in the wire is called induced current. A stationary wire in the presence of a changing magnetic field also has an induced current. A changing magnetic field can be produced either by moving a magnet near to the stationary wire or by using alternating current. A stationary wire in a magnetic field which is not changing will have no current induced in it. You will sometimes see this effect described as induced voltage. Strictly speaking, you will only get an induced current in the wire if it is part of a complete circuit. A wire which is unconnected at both ends will have a difference in voltage between the ends (a potential difference) but current can only flow when the wire is in a circuit. Induced current is used in electricity generation and transformers.Another AnswerThere is no such thing as an 'induced current', only an 'induced voltage'. Current will flow only if the conductor into which the voltage is induced forms part of a closed circuit.
Difference between back EMF and induced EMF?
An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!
In a two coil system the induced potential difference in the secondary coil depends on?
In a two-coil system, the induced potential difference in the secondary coil depends on several factors: the rate of change of magnetic flux through the coil, the number of turns in the secondary coil, and the strength of the magnetic field produced by the primary coil. According to Faraday's law of electromagnetic induction, the induced voltage is proportional to the rate of change of the magnetic field and the coil's turns. Additionally, the orientation and distance between the coils can also affect the induced potential difference.
Which mechanism is the cause of the difference in color between the wild Indian ring necked parakeet and the domesticated Indian ring necked parakeet?
Hybridization or induced mutation
Why an induction motor will never run at synhoronous speed?
An induction motor relies on low-frequency currents induced in the rotor by the difference in speed between the rotor and the rotating magnetic field. At sychronous speed the induced current is zero therefore the torque is also zero.
What happens to the force between charged and uncharged objects as the distance between them increased?
as the distance is increased statically induced charge in the uncharged object reduced to a minimum. Thus coulombic force which is directly proportional to the product of the charges tends to 0.
