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!
What is self induced?
When a current in a coil increases or decreases, there is a change in magnetic flux linking the coil,an e.m.f. is induced. This is called self induced e.m.f. and the process is called self induction.
What determines whether an induced current is a direct current or an alternating current?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. The direction of the induced voltage is determined by the direction of the changing current that induces that voltage, because the induced voltage will always act to oppose that change in current. So, if the current is increasing, then the direction of the induced voltage will act to opposethe increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustainthat current.
Why voltage induced when moving coil cuts flux?
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows
What is induction of electric current?
According to Farady's law, whenever the flux linking with the coil changes, emf will induce in that coil.Actually the material should oppose the flux changes, that opposition is the induced current. Induced current will set own flux, opposite to that of the flux changes.For further details, refer lenz law.
Is every simple graph on n vertices is isomorphic to a subgraph on kn?
yes
Given an undirected graph G and an integer k?
Given an undirected graph G=(V,E) and an integer k, find induced subgraph H=(U,F) of G of maximum size (maximum in terms of the number of vertices) such that all vertices of H have degree at least k
What is subgraph in given graph?
If all the vertices and edges of a graph A are in graph B then graph A is a sub graph of B.
Is induced voltage and induced currrent the same?
No, induced voltage and induced current are not the same. Induced voltage refers to the electromotive force that causes a current to flow in a conductor, whereas induced current is the flow of electric charge in response to the induced voltage. The relationship between induced voltage and induced current is governed by Ohm's Law.

How do you find subgraph in a graph?
simply draw separate graph from the graph from which you have to find the subgraphs, remove exact one edge ont time and proceed to the till end.
What does the word induced mean?
INDUCED has two meaningsSucceed in persuading or influencing (someone) to do something.Bring about or give rise to: "measures that induced a change"

Is flow of induced current necessary when induces emf is being produced?
There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.
Difference between statically and dynamically induced emf?
STATICALLY INDUCED EMFThe 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 EMFThe 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
