Given a list of steps and an additional step, determine where the step fits into the original list of steps. A correct answer, correctly places the given step into the set of steps so that it creates a new plausible set of steps. Output must be formatted as 'After step n', where n is the step number after which the given additional step is to be inserted.

 After step 2. 

Steps: (1) A conducting metal, like copper, is wrapped around a piece of metal (2) An electrical source, like a battery, produces an electrical current (3) The electrical current creates a magnetic field around the wire, magnetizing the metal (4) The magnetic field can be turned on and off by starting or stopping the electricity source  
Where does the following step fit into the given list of steps: The electrical current flows through the wire 

 After step 2.
