Which factor does NOT influence the magnetic flux in a transformer?

In a transformer, magnetic flux is largely influenced by the core material, the number of turns in the winding, and the supply voltage. These factors directly contribute to the efficiency and effectiveness of the transformer in transferring electrical energy through magnetic fields.

The core material significantly affects how well magnetic fields can be established and sustained within the transformer. A higher permeability core material allows for greater magnetic flux.

The number of turns in the windings determines the voltage transformation ratio of the transformer. More turns in the winding can lead to a higher induced voltage due to the increase in magnetic flux linking the windings.

The supply voltage contributes to the magnetic flux as well, as higher voltage levels can increase the magnetic field strength, thereby increasing the magnetic flux within the transformer.

Temperature, while it can affect resistance and other properties of the materials involved, does not directly influence the magnetic flux in the same way that the core material, the winding turns, and the supply voltage do. Therefore, temperature is not a key factor in determining the magnetic flux within a transformer.
