Web2 dec. 2024 · You keep thinking of it as an EMF induces a changing flux. There is no induced flux. The flux changes, thus inducing an EMF. As for why the flux through each coil is the same, this is because the coils are wrapped around a material that keeps the field within the material, so the flux through both coils must be the same. $\endgroup$ – WebThe MMF which sets up the magnetic flux is analogous to the EMF. The MMF is equivalent to a number of turns of wire carrying an electric current. If either the current through a coil (as in an electromagnet) or the number of turns of wire in the coil is increased, the MMF will be higher; and if the rest of the magnetic circuit remains the same, the magnetic flux …
