From the reading above, what are the patterns for the angle of incidence and the angle of refraction? What do these patterns say about the characteristics of the two selected media?

an energy transformation flow diagram is shown

where is it ?

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
