what are the assumptions of an ideal transformer?

An ideal transformer operates under several key assumptions: it has no losses, meaning it is 100% efficient with no energy lost as heat or magnetic leakage. The core material is assumed to have infinite permeability, allowing for perfect magnetic coupling between the primary and secondary coils. Additionally, the windings are considered to have no resistance, leading to no voltage drop during operation. Lastly, it assumes that the magnetic field is static and that the transformer operates under sinusoidal steady-state conditions.
