Transformer is an example of statically induced emf. Here the windings are stationary,magnetic field is moving around the conductor and produces the 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 Statically induced EMF is defined as "The emf induced in a coil due to change of flux linked with it is called Statically Induced EMF." Transformer is an example of statically induced emf. Here the windings are stationary and the magnetic field is moving around the conductor and produces EMF. This phenomenon takes place in electric generators and back emf of motors and also in transformers. Thus by following either of the two process the conductor cuts across the magnetic field and the emf is induced in the coil. An emf induced by motion relative to a magnetic field is called a motional emf. is going to induce a magnify let's again I can take my right hand out and try to draw my right hand and we can see now the direction of my fingers go in are that way and notice we're looking at the inside of the surface so the Induced emf, self induced emf, mutually induced emf, self inductance, mutual inductance definition, explanation and formula. The induced EMF in this way is known as dynamically induced EMF. It is so called because either magnetic field or coil is moving in this case. 1. Direction of Dynamically Induced E.M.F The direction of induced e.m.f. can be decided by using two rules. The Lenz's law states that, The direction of an induced e.m.f. produced by the electromagnetic induction is such that it sets up a current which always opposes the cause that is This emf is dynamically induced emf. e.g. Emf induced in generators, alternator. Dynamically induced EMF: An EMF induced in a conductor by physical movement of conductor or magnet with respect to magnetic Alternators, generators, motor, are the examples of dynamically induced EMF. Faradays Law: The induced emf along a round-trIp path is equal to the rate of change of the magnetic flux on the area encircled by the path. Lenzs Rule: The induced electric field would drive the current in the direction to make the magnetic field that attempts to keep the flux constant. Dynamically Induced E.M.F. In Figure 1 (a), the conductor A is shown by the cross-section within the uniform magnetic field. It moves at right angle The DC generators work on the principle of production of dynamically induced e.m.f. in the conductors which are housed in a revolving armature lying Electromagnetic induction has found many applications, including electrical components such as inductors and transformers, and devices such When the coils are stationary, no current is induced. But when the small coil is moved in or out of the large coil (B), the magnetic flux through the large coil Statically Induced EMF: If a stationary conductor(conductor does not change its position) placed in a changing magnetic field as a result of the flux linkage with As the induced EMF caused by the relative motion of the conductor and magnetic field that's why it is called Dynamically Induced EMF. Nature of Induced E.M.F Points : Nature of Induced E.M.F, Dynamically induced emf, Stationary induced emf, Self Induced emf The Emf be able to induced by revolving a coil in a magnetic field or coil reserved stationary and flux linked with it changes. The induced emf can be alienated in two type. Nature of Induced E.M.F Points : Nature of Induced E.M.F, Dynamically induced emf, Stationary induced emf, Self Induced emf The Emf be able to induced by revolving a coil in a magnetic field or coil reserved stationary and flux linked with it changes.

Faradays law Direction of induced emf The direction of induced emf and induced current in a conductor does not remain same. All induction, including the examples given so far, arises from some change in magnetic flux ?. For example, Faraday changed B and hence ? when opening and closing the 4. Is an emf induced in the coil in Figure 5 when it is stretched? If so, state why and give the direction of the induced current.
