In a transformer the magnitude of mutual flux
WebSep 15, 2024 · The basic operating principle of a transformer is the work of mutual induction between the primary and secondary windings which are linked by a common magnetic flux through the transformer core. The core provides a path of low reluctance for the magnetic flux to pass through. ... the greater the magnitude of the current, the greater will be the ... WebApr 12, 2024 · The magnitude of the generated flux density is also different. Is the reason for this phenomenon simply that the windings are different? The difference in flux density will affect the voltage on the secondary side. Therefore, the validity of this comparison has to be considered. 4.
