Explanation:

​matter & Energy Waves are created when a source of energy (force) causes a vibration. A vibration is a repeated back-and-forth or up-and-down motion. ... While all waves can transmit energy through a medium, certain waves can also transmit energy through empty space. A medium is a material through which waves can travel.

c. magnitude and direction

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.
