Week -2

Aim:

To make a simulink model of Doorbell using a solenoid block with the following details. the switch is closed for 2 seconds and then released. obsereve the physical movement

Working principle of Doorbell:

The heart of a doorbell is an electromagnet. Electromagnets are coils of wire wrapped around a small piece of magnetic metal. When electricity passes through the wire, it creates a magnetic field around the wire. When we press a doorbell button, you complete an electrical circuit that allows household electricity to flow through the doorbell's internal electromagnet. The magnetic field generated by the electromagnet is then used to power a mechanism that creates the doorbell sound.

Blocks used in the Simulink model:

Battery

pulse generator

switch

solenoid

ideal transitional motion sensor

electrical reference

mechanical reference

scope

Pulse generator

output:

doorbell is modelled to ring for 2 seconds and stopped for 2 seconds
