WebMar 23, 2024 · The correct answer is Mutual Induction. Concept: Transformer works on the principle of mutual induction of two coils Mutual induction is defined as the property of the coils that enables them to oppose the changes in the current in another coil.
WebThe fluxes within the transformer core remains constant irrespective of the load. If in case the load changes, the current in secondary side changes which results in change in … WebThe mutual inductance will be maximum when maximum field lines due to one coil pass through the other. In such a situation, magnetic flux linked will be maximum. Therefore, in …
WebIn physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell. WebThe magnitude of the electromagnetic induction is directly proportional to the flux density, ... The changing magnetic flux in the iron core of a transformer above will induce an emf, not only in the primary and secondary windings, but also in the iron core. The iron core is a good conductor, so the currents induced in a solid iron core will be ...
