I recently learned that if you send direct current through the primary coil of a transformer, no power would be transferred to the secondary circuit? Why is that?

The field lines do not have to be moving. The changing magnitude and direction (+/-) of the primary current generates a changing flux value, which in turn induces the changing secondary output voltage.David Lewis said:Referring to the picture, if most of the magnetic flux stays inside the iron core, how do moving field lines cut through the secondary coil?
David Lewis said:If the flux value (concentration of field lines) changes, do the magnetic field lines move?
A DC-Transformer circuit is a type of electrical circuit that uses a transformer to convert direct current (DC) electrical energy into a different voltage level. This can be achieved by altering the number of windings in the transformer's primary and secondary coils, which changes the voltage ratio between the input and output.
A DC-Transformer circuit works by using a transformer to convert the input DC voltage to a different output voltage. The transformer consists of two coils of wire, known as the primary and secondary coils, which are wound around a core. When a DC voltage is applied to the primary coil, it creates a magnetic field in the core, which induces a voltage in the secondary coil. This voltage can then be stepped up or down depending on the number of windings in each coil.
A DC-Transformer circuit is commonly used in electronic devices to convert the voltage from a power source to a level that is suitable for the device's operation. It is also used in power distribution systems to step down high voltage power to a lower voltage, which is safer and more efficient for household use.
One advantage of using a DC-Transformer circuit is that it allows for the conversion of DC voltages to different levels, which is not possible with a simple resistor or capacitor. It also provides electrical isolation between the input and output, which can protect devices and users from potential hazards. Additionally, transformers have a high efficiency and can handle large amounts of power without significant losses.
One limitation of a DC-Transformer circuit is that it can only convert DC voltages, so it is not suitable for use with AC voltages. Additionally, the transformer must be designed and sized properly for the specific application to ensure efficient operation. Lastly, transformers can introduce losses and heat, so they may require additional cooling or insulation measures.
