What is unit of dynamically induced emf?

The term dynamically induced emf refers to an emf that occurs in a conductor when it moves across a magnetic field; for example, in the figure, when conductor A with length L moves across flux density B with velocity V, the term dynamically induced emf is present.

What is dynamic inductance?

The dynamic inductance makes it possible to determine the relationship between the currents determining a transient process in coils and the instantaneous ux linkage.

What is mutually induced emf?

With a change in the current of one coil, the flow also changes, causing EMF to be produced in the other coil; this phenomenon is known as mutual induction. Mutual induction is defined as the property of the coils that allows it to oppose the changes in the current in another coil.
What factors dynamically induce emf depends?
induced e.m.f for a coil of wire depends on four things:

  • Magnetic strength of the core in the coil of wire. (stronger –> bigger emf)
  • Number of turns of wire in the coil (more turns –> bigger emf)
  • The cross-sectional area of the coil (bigger area –> bigger emf).
  • how quickly you insert and remove the magnet from the coil.

There are two types of Induced EMF,

  • EMF that is statically induced.
  • EMF that is dynamically induced.
  • self-generated electromagnetic field.
  • induced by both parties.
