during some interval of time energy flows from the source to the coil-core assembly and during some other interval of time energy returns to the source. However, the energy flowing in is greater than the energy returned. Therefore, during a cycle of variation of the applied field,...

A compass needle is a magnet (a weak one), and it tends to line up in such a way as to point its "north pole" towards the North Pole of the planet. Based on what you have learned so far, what do you think will happen if you put the compass near a wire carrying an electric c...
