school bell consists of a hammer and a gong in an arrangement which is connected to the external source of current.
when the current passes through the arrangements, small hammer hits the gong repeatedly causing it to vibrate.These vibrations travel in the air in the form of compressions and rarefactions which beaches are ear and we hear it sound.
