Let’s say our clock should make a nice slow tick-tock. It ticks or tocks every time it reaches one end of its cycle. If it takes exactly one second from tick to tock, what is the total period of the pendulum?

c) power lifting, will be your answer.

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.
