When a current flows through an electric bell what will happen to the armature?
When a current flows through an electric bell, it creates a magnetic field that causes the armature, attached to a spring, to be attracted towards the electromagnet. This movement causes the armature to strike the bell, producing a ringing sound.
Is ringing a bell a chemical change?
No. I think :P
Application of electric bell?
An electric bell works when a current is passed through a coil, generating a magnetic field that attracts a metal armature connected to a clapper which strikes the bell. This mechanism creates a ringing sound, making electric bells commonly used in alarm systems or as doorbells.
According to the Navigation Rules a rapidly ringing bell every minute signals what?
A rapidly ringing bell every minute signals a vessel at anchor.
Cite an experiment to show that sound needs a material medium for its propagation?
Obtain a bell jar with a valve at the top, place the bell jar on a smooth flat surface. connect the valve to a vacuum pump through a rigid hose. Place a manual wind up spring alarm clock under the bell jar. Seal the bottom lip of the bell jar with petroleum jelly and ensure there are no gaps between the bell jar and the surface. Note the ticking of the clock. Start the vacuum pump and observe when the internal pressure begins to drop. Stop the vacuum pump and close the valve. Listen to the clocks ticking. Re start the vacuum pump and note the pressure drop, close the valve and listen to the ticking clock. As the pressure decreases the sounds of the clock will get fainter and fainter because there is less of the material medium (Air) to transfer the sound.
When ringing bell is touched no sound is heard?
If the bell is not making a sound when touched, it may be due to a loose or disconnected internal component such as the clapper or striker. It could also be caused by a worn-out or damaged sound-producing mechanism inside the bell. Checking and repairing these components should help restore the sound when the bell is touched.
Why does the sound stop when the ringing bell of the cycle is touched?
When the ringing bell of a bicycle is touched, the metal vibrations that produce the sound are dampened by the contact with a solid surface or object, disrupting the sound wave propagation and causing the sound to stop. This interference interrupts the resonance necessary for the bell to continue ringing.
Why a sound of ringing bell inside vacuum chamber cannot be heard?
Sound requires a medium, such as air, to travel through. In a vacuum chamber, there is no air or medium for the sound waves to travel through, so the ringing bell cannot be heard.
What is a sound of a bell?
A bell produces a clear ringing sound when struck. The sound is created by the vibration of the bell material, which amplifies and resonates to produce the ringing tone.
Why a bell ringing inside a vacuum chamber cannot be heard?
sound needs a medium to travel. material medium is necessary for propogation of sound. in vaccum sound do not travel. that's the reason why we are not able to hear sound in this case. Jordi101
What is the ringing sound of bell is called?
bong, call, chime, clang, knell, peal, signal, sound,
What energy tranformations occur in ringing bell?
When a bell is rung, mechanical energy from the person ringing the bell is transferred to the bell causing it to vibrate. The vibration of the bell produces sound energy as it moves through the air, creating the ringing sound. So, the energy transformations involved are from mechanical energy to sound energy.
Is bell a noun?
Yes, the word 'bell' is both a noun (bell, bells) and a verb (bell, bells, belling, belled).The noun 'bell' is a word for a hollow metal device that makes a ringing sound when struck; an electric device that makes a ringing sound; a ringing sound used as a signal; a word for a thing.The verb 'bell' is to take the shape of a bell, to flare; to equip with a bell or bells.
What is the sound that bell makes?
The sound that a bell makes is known as a "ring" or "toll" If it's a little bell, it's a ringing noise. "Ding" If it's bigger, it's tolling. "Dong"
Why cant you hear a bell inside of a vacuum jar?
Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
Can a bell ringing under water be heard?
yes bell rung under water can be heared
Why does a doorbell produce a ringing sound?
A doorbell produces a ringing sound by using an electromagnet that creates a magnetic field when the button is pressed, attracting a metal rod to strike a chime or bell. This action creates vibrations in the bell, producing the ringing sound that we hear.
