Answer

Brief Explanations:

When a door - bell button is pressed to complete a circuit, current flows through an electromagnet. The electromagnet attracts an iron piece attached to a hammer. The hammer strikes the bell. After the strike, a spring pulls the iron piece and hammer back into place. Then the cycle can begin again if the button is pressed again. So the last step in the sequence is that the cycle begins again.

Answer:

The cycle begins again.
