What is induced subgraph?
April 25, 2008 7:17PM
Any subset X ⊆ nodes(G) induces a subgraph G[X] of G, where G[X] has nodes X and G[X] contains all arcs of G which join nodes in X.
G′ is a full (or induced) subgraph of G if G′ = G[X] for some X ⊆ nodes(G).

What are the Example each for self induced and mutually induced emf?
How do you differentiate induced emf from induced current?
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. Comment Technically, 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!

How was current produce or induced?
Current is induced and not produced. when an electric wire is passed through magnetic field the current is induced in the electric wire, this electric wire is enamelled copper conductor of a rotor. Answer Current is never 'induced' into a conductor. It is a voltage that is induced. If that conductor is then part of a complete circuit, then the induced voltage will cause a current to flow. The induced voltage will occur even when the conductor is open circuited.
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 oppose the increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustain that current.

Difference between statically and dynamically induced emf?
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

Who formulated a law for determining the direction of the induced current in a conductor?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. If the conductor into which that voltage is induced forms a complete circuit, then a current will result. But it's the voltage that's induced, NOT the current! The direction of the induced voltage is explained by Lenz's Law which, in simple terms, tells us that the direction of the inducted voltage is always such that it will oppose the change in current that causes it. So the induced voltage will oppose any increase in current, but will act in the same direction as a reduction in current.
