Advantages High magnetic permeability: Ferromagnetic materials have high magnetic permeability, which means they can generate a large magnetic induction intensity under a relatively small magnetic field strength. In a transformer, using ferromagnetic materials for the core allows most of the magnetic field generated by the windings to be concentrated inside the core, enhancing the magnetic field coupling effect. This, in turn, improves the electromagnetic conversion efficiency of the transformer

Using a toroidal transformer core offers several advantages:Reduced Magnetic Losses: The structure of the toroidal core provides a more uniform and efficient path for magnetic flux, which helps reduce hysteresis and eddy current losses. Its circular cross-section allows the magnetic field generated by the winding currents to distribute more evenly throughout the core, improving efficiency.Lower Noise: Toroidal transformers generate less mechanical noise during operation. This is because the toro
