In an electric bell the electric current stops again and again give reason
Answers
Explanation:
As the electric circuit is closed by pressing the switch the current flow through the coil and the core of the Electromagnet get magnetize and therefore its attract the armature by the arrow .Due to movement of the armature the hammer strike the ground and the bell ring .
As the moment when the armature a move toward the Electromagnet due to magnetize attraction the connection between the strip and the screw break due to which the flow of current in the coil stop .
Continuously the Electromagnet gets demagnetize and the armature flies back to its original position due to the spring effect of the strip now the armature again touches the screw which result in the flow of current in the coil the Electromagnet reaction is magnetism and the armature it again attract , so the hammer again strike the gong this process continues .
The process of make and break of circuit goes on and the hammer strikes the gong repeatedly show the bell ring As Long the switch is kept pressed
