Solution
The correct option is B Make and break
The working of an electric magnet is based on the magnetic effect of the current. When the key is pressed the circuit gets completed and current passes through it causing the electromagnet to get magnetized which in turn attracts the armature. This movement of the armature causes the hammer to strike the gong. However, when the armature moves towards the gong the connection between the spring strip and adjusting screw is lost which breaks the circuit, and the current flow is stopped thus demagnetizing the electromagnet. This causes the armature to return to its original position and it is thus pulled back due to the spring effect of the spring strip. This process is called a make and brake circuit.
