How will magnetic minerals align in a rock if earth has no magnetic field?
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
Why do electronics get destroyed when a magnet is near it?
Magnets do not destroy electronic equipment but they do influence their behaviour of shadow mask Colour Television Tubes in that the shadow mask can become manetised from a magnet close by. Magnetization causes incorrect beam landing on the pic tube which shows as multi coloured patches on the screen . The effect can be cancelled out by degausing the CRT using a degauss wand . All CTV have an auto degauss system to take care of impurities caused the earths magnetic field .
What are the common uses of magnets?
let's see where do we begin. The lawn mower, riding or push uses magnets to keep the engine running. Almost any household appliance with a wound motor uses magnets. Everything from can openers to refridgerators has to have a magnet to keep it going. Also ANY speaker, in a car, TV set, stereo, has a magnet.
Can an electron at rest be set in motion by the magnetic field?
Sure. A charge in a magnetic field experiences a force. A force acting on a mass produces acceleration. Remember the old-style TV sets that were about 6 feet deep from front to back ? That type of picture tube is called a 'CRT', for "cathode-ray tube'. There's a hot wire at the back end of the picture tube that produces a cloud of electrons. The front face of the picture tube has a high positiver voltage on it, to attract the negative electrons to the front. On the way there, the electrons have to go through these magnet coils that are around the neck of the picture tube. The magnetic field inside the neck pulls the stream of electrons left and right, up and down, left and right, and that's how they draw a picture on the front face when they get there.
What is magnetic bearing?
It is a bearing (a direction) based on a magnetic compass reading.
What may cause a compass needle to point to a television rather than earths magnetic north pole?
The television or something in it must be generating a magnetic field.
How does a TV take advantage of magnetic forces?
A television system takes advantage of magnetic forces by using electromagnets. These magnets control the electron beams, causing them to scan top to bottom and left to right.
What type of rays give television signals?
Television technology is based mainly on the manipulation of the electro- magnetic spectrum.
What does a magnet do in the television?
Usually there is no ferrous magnet within the TV - i.e a permenant magnet. Rather a solenoid is used to generate a changing magnetic field. Simply put, the magnetic field is used to focus the cathode ray that creates the image on your television's screen.
What makes the tv work?
electro magnetic waves that turn into sound energy and changes info
What would happen if I placed a magnetic light strip on the back of my LCD TV, would it break the TV?
Probably yes !
What do you use in a vacuum to bend electronic beams?
Either an electrostatic field or a magnetic field. Each type is used in cathode ray tubes: generally, electrostatic in oscilloscopes, magnetic in television and computer CRTs.
Is there a material that will stop a magnetic pull but is not magnetic itself and will stop a computer phone or TV from breaking if a magnet is brought near it?
I don't believe there is.Ferromagnetic materials concentrate magnetic fields within themselves, but they are, as you might have guessed from the name, magnetic.A Faraday cage can be nonmagnetic (you could make it out of, say, copper) and will keep out electromagnetic radiation, but does nothing against a static magnetic field.
What is the name of the song in the new Living TV advert?
Magnetic man ft John Legend - getting nowhere
Why can't electricity pass threw a magnetic field?
An electric current has no trouble at all passing through a magnetic field, however it is deflected. This is how the old CRT picture tubes that used to be used in TVs and computer monitors operated. In space electric currents deflected by magnetic fields actually follow helical paths along the lines of magnetic flux.
Your tv has a rainbow effect?
This coloured effect is caused by residual magnetic fields on the shadowmask of a cathode ray tube tv. When a tv is switched on an alternating electrical current is passed through a coil looped around the crt face, this eliminates these stray magnetic fluxes. There may be a fault with this circuit. A magnet brought into proximity with the tv screen can permanantly magnetise the shadowmask or flex it out of position.
When a sound speaker comes too close to a color tube television the color of the television becomes distorted?
The magnetic field from the speaker is interrupting the flow of electrons.
