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.

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
What is the difference between inductive and non inductive resistor?
INDUCTIVE RESISTOR:Any circuit in which change in current is accompained by change in flux and therefore by inuced emf is said to be inductive. NON-INDUCTIVE:if a double wire is wound arround an insulating rod,the emf can not be induced because the wire is doubled back on itself at its centre and the doubled wire is wound arround an insulator.thus every turn of the coil has adjascnt turn which is carring current in opposite direction.the magnetic field generated by each other cancel out each other effect.hence no emf is induced in coil and coil has zero inductance.
How can you say that ac emf is induced in the coil?
When we place a current carrying conductor in a magnetic field emf is induced in a coil. we can knoe it by connecting voltmeter.
What is Back emf of DC motor?
In dc motor, the armature conductors are revolving in the magnetic field and emf is induced in the armature conductors. The direction of the induced emf is in opposite direction to the applied voltage as per Flemings left hand rule. So, the induced emf in motor is called as back emf or counter emf. Vydehi
The direction of statically induced emf can be found by which law?
Lenz's Law
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 the induced emf in case (a)?
In case (a), the induced emf is the electromotive force generated in a coil or conductor due to a changing magnetic field.
What is the induced electromotive force (EMF) in this loop?
The induced electromotive force (EMF) in a loop is the voltage generated when there is a change in magnetic field within the loop.
What is the average induced emf in the loop?
The average induced electromotive force (emf) in the loop is the average amount of voltage generated in the loop due to a changing magnetic field.
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!
How is emf induced in an alternator?
EMF or electromotive force, i.e.Voltage, is generated when the magnets inside the alternator turn within the wire coil of the alternator.
Does motional emf call induced emf?
yes indused emf is also called motional emf. If an open coil is subjected to a variable magnetic field, at the ends of the coil a potential difference is induced which is called induced emf. If a coil is connected to an emf source and switched on, the rising current will produced an variable magnetic field which in turn produces an emf. It is called back emf.

What is the induced emf in the coil when a magnetic field is applied?
When a magnetic field is applied to a coil, it creates an induced electromotive force (emf) in the coil. This emf is generated due to the change in magnetic flux through the coil, according to Faraday's law of electromagnetic induction.
How are motion induced electric fields and motional emf related in the context of electromagnetic induction?
Motion-induced electric fields and motional emf are related in the context of electromagnetic induction because both phenomena involve the generation of an electric field due to a changing magnetic field. When a conductor moves through a magnetic field, it experiences a motional emf, which is the voltage induced in the conductor. This motional emf is caused by the motion-induced electric fields that are generated in the conductor as a result of the changing magnetic field. In essence, motion-induced electric fields lead to the generation of motional emf through electromagnetic induction.
Why change in flux causes generation of electricity?
whenever flux changes an emf is induced if ressistance is connected to that side current is generated.
What are the factors that determines the size and direction of the generated emf?
The size of the generated electromotive force (emf) is determined by the rate at which the magnetic field changes within a circuit, and the number of turns in the coil. The direction of the emf is determined by Lenz's law, which states that the induced current will flow in a direction that opposes the change in magnetic field that produced it.
