Many doorbells work in the way pictured below. An electromagnet, which is made up of a coil of wire wrapped around a metal core,
causes a metal beater bar to rapidly move up and down. This causes the beater at the end of the bar to strike a bell repeatedly. How does the electromagnet cause the beater bar to move?
when current is allowed to pass through the electromagnet it produces and magnetic field which eventually causes the bell striker to hit the gong
Explanation:
An electromagnet is a coil of wire around a magnet or metal.
when the door bell button is held down, current flows into a transformer which them steps down the current and passes it to the electromagnet, a magnetic field is created which them makes the bell-striker to hit the gong. in a series of make and break of the circuit, the process is repeated multiple times causing that buzzer sound.
the door bell button completes the circuit but when the bell-striker hits the gong the circuit is broken, the striker returns to its position and completes the circuit again and the process is repeated. this continues as long as the door bell button is held down. it is this make and break of the circuit that produces that buzzer sound of the doorbell

However, nuclear power plants generate significant amounts of radioactive waste. That is why we should not choose nuclear energy over fossil fuel power plants.</span>
