|On a field Ram and Shyam were playing football. Suddenly, a player kicked out the ball outside the field and the ball reached an electric power substation. One of the players was planning to go and bring back the ball to the field but, Ram and Shyam stopped him saying that it is dangerous to go to the substation as warmed up body can be caught by the strong magnetic field, which is created by high voltage current in conduction of the switch yard and that may result in death.|
