explain the construction and working of an electric bell.

consruction- it consist a gong,an electromagnet,a soft iron rod (armeture) and a contact screw

working-when current passes through electromagnet it becomes magnet and attract the armeture.so,the hammer strikes and attract the armeture. threfore,contact with screw breaks and electromagnet does not behave like a magnet now.so,armeture comes down therefore contact with screw is estaiblished. this cycle keeps on repeating.

An electric bell is a mechanical bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing or clanging sound. Electric bells have been widely used at railroad crossings, in telephonesfire and burglar alarms, asschool bellsdoorbells, and alarms in industrial plants, but they are now being widely replaced with electronic sounders.


How an interrupter-type electric bell works. The bell (B) is struck by the clapper(A), actuated by the electromagnet (E). This opens the electrical contacts (T) attached to the clapper arm, interrupting the current to the electromagnet

1. Construction-:

  • electric bell works on magnetic effect of electric current
  • it consists of a coil wire wound on an iron piece
  • the coil acts as an electromagnet
  • an iron strip with a hammer at the is kept close to electromagnet
  • there is no contact screw near the iron strip

2. Working

  • when the iron strip is in contact with screw,the current flows through the coil which becomes an electromagnet
  • It the pulls the iron strip.In the process,the hammer strikes the gong of the bell to produce a sound
  • when the electromagnet pulls the iron strip,the circuit breaks
  • the coil is no longer electromagnet
  • it no longer attracts the iron strip
  • the iron strip comes backs to its orignal position and touches the contact screw again
  • this again complete the circuit and the coil again again attracts the iron strip and strikes the gong
  • this process is repeated in quick session
  • the hammer strikes the gong everytime the circuit is complete
  • this is how the bell rings

working of an electric bell:

step 1- when the switch of the electric bell is pressed, the current starts flowing through the circuit to the electromagnet.

step 2- this electromagnet attracts the soft iron strip and it moves away from the screw. this causes the hammer to strike the gong.

step 3- as the iron strip moves away from the screw, it breaks the circuit and the current stops flowing. now the electromagnet loses its magnetism and the soft iron strip comes back to its original position and makes contact with the screw again. this completes the circuit and the process is repeated as long as the switch is pressed and causes the hammer to hit the gong repeatedly. thus, the sound of the electric bell is heard

An electric bell is an electrical device with mechanical parts that moves when current is passed through it. The bell functions by means of an electromagnet. It produces repetitive buzzing or clanging sound.

The hammer is attracted towards the electromagnet whenever the circuit is complete. The circuit breaks whenever the hammer moves towards the electromagnet. When the circuit breaks the electromagnet doesnt attract the hammer. The hammer comes back to its original position due to spring effect. As the hammer comes back to its original position, it touches the metal connector, the circuit is complete again. This cycle continues till the time the key is kept ON.

Electric bells are used as school bells, doorbells and also at rail road crossings.

The bell orgong(B), which is often in the shape of a cup or half-sphere, is struck by a spring-loaded arm(A)with a metal ball on the end called aclapper, actuated by anelectromagnet(E). In its rest position the clapper is held away from the bell a short distance by its springy arm. When anelectric currentis enabled to pass through the winding of the electromagnet (via a closing of the switch(K)i.e.pressing the door bell) it creates a magnetic fieldthat attracts the iron arm of the clapper, pulling it over to give the bell a tap. This opens a pair ofelectrical contacts(T)attached to the clapper arm, interrupting the current to the electromagnet. The magnetic field of the electromagnet collapses, and the clapper springs away from the bell. This closes the contacts again, allowing the current to flow to the electromagnet again, so the magnet pulls the clapper over to strike the bell again. This cycle repeats rapidly, many times per second, resulting in a continuous ringing.

 One end of armature winding is connected to terminal T1 and the other to a spring, which is mounted on     a soft iron strip. A rod is attached to the armature and the free end of the rod carries a small hammer,     which strikes a bell. A very light spring is attached to a screw, which is joined to terminal T2. WORKING OF ELECTRIC BELL       The electric circuit is completed through a battery and push switch button connected to the terminal T1     and T2. When the push button is pressed the electric circuit is completed and the armature is attracted     towards the electromagnet as a result, the small spring gets detached from the screw due to which the     electric circuit is broken and the electromagnet is demagnetized. Hence, the attraction disappears and     the armature is brought back by the spring to its original position. Contact of the spring with the screw is     now remade, which completes the electric circuit. The action is repeated over and over again     consequently. The armature vibrates and hammer attached to it strikes the gong and the bell rings and     sound is produced.

     An electric bell consists of an iron core, on which is wound a wire as a coil. One end of the coil is connected to one terminal of a battery, and the other end to a steel rod that acts like a spring for the hammer touching the screw contact. The other terminal of the battery is connected to the screw contact with a switch in the middle.


Working of an electric bell

Electric current flows through the coil when the switch is ON, and the iron core acts as an electromagnet. The iron core attracts the hammer towards it. The hammer hits the bell and produces a sound. The circuit breaks at the screw contact when the hammer moves towards the iron core. At this point, the iron core ceases to be an electromagnet. The hammer is pulled back to its original position due to the spring action of the steel rod, and then touches the contact again to complete the circuit. The circuit is completed and current flows through the coil again, and the hammer strikes the bell again. The process repeats itself and you hear a ringing sound since the hammer keeps hitting the bell, until the switch is released.

*An electric bell consists of coil of a wire wound on an iron piece. This acts as an electromagnet.
*There is a contact screw wear the iron strip.
*It also consist of a battery and a switch.


WORKING OF A BELL
*When the iron strip is in contact with screw, the current flows through the coil which becomes electromagnet.
*It then pulls the iron strip. The hammer at the end of the strip strikes the gong of the bell to produce a sound.
*However ,when the electromagnet pulls the iron strip, it also breaks the circuit due to which the coil no longer acts on electromagnet.
*The iron strip bounces back into its original position and completing the electric current makes the coil electromagnet.
*This process is repeated in quick succession. Every time the circuit is completed, the coil starts behaving as an electromagnet.

An electric bell consists of the gong,hammer,2 electromagnets, wire , battery , switch ,soft iron piece , & screw . When we on the switch then the circuit is complete then the electromagnet will attract the sift iron piece , and the hammer will hit the gong , but then the connection losses because the screw no longer touches the iron piece ( the interrupter ) and the hammer comes back to its place. This thing continues and we hear the tan ,tan tan sound .

Construction of Electric bell
The electric bell has a u-shaped Electromagnet. A small iron bar called armature is held in front of the poles. The lower end of armature is attached to a flat spring and the spring is itself fixed into a metal bracket. The upper end of armature has a hammer attached to it. There is a contact screw which just touched the armature at point E. A metal gong is fixed near the hammer. The electromagnet is connected to a battery push button switch and armature in a circuit.
Working of Electric bell
1. When we press the switch, the electric circuit of the bell is completed and a current passes through the coil of the electric electromagnet and it gets magnetized. The electromagnet attracts the armature towards itself, the hammer attached to it strikes the gong and produces a ringing sound.
2. When the armature moves towards the magnet, it's contact with the contact screw is broken at point E. Due to this the electric circuit breaks and no current flows in the electromagnet coil. The electromagnet loses its magnetism and the armature is no longer attracted by it. The flat spring brings back the armature to it's original position and the hammer moves away from the gong.
