TV's that used the old cathode ray tubes (CRTs) had magnets around the neck of the tube, to control the electron beam as it passed, to paint the picture on the tube face.
The majority of the magnets were electromagnets (coils of wire) fed with an electronic signal. to give fine and precise control. There were however, on early tubes, small permanent magnets for correcting errors in the curvature of the glass screen, mounted around the tube.
Modern TV's using LCD or plasma screens do not use magnets.
Coils are still found inside, forming tuned circuits for the radio section and wave form generators.
Some TV's may have relays inside, for controlling the standby or switching functions, these have electromagnets inside them.
Electricity is the medium by which all electronic products work.

How do we use magnets in everyday life?
Magnets are actually used in most of the items we use today, such as: * car doors * door hinges * computers * hoovers * blenders * CD players * washing machines * fax machines * escalators * elevators * loud speakers * credit cards * TVs * fridge doors * toys * jewelry * electric toothbrushes * junk yards * roller coasters *fridge magnets
What are two household items that use magnets to work?
Magnets are used in a number of household items. First, anything with a motor: Refrigerator Dishwasher Ceiling Fan Garbage Disposal Furnace Additionally, the seal around your refrigerator door may have a magnet to get a good air seal. Older kitchen cabinets had magnetic latches as well.
What magnets are used for?
Some magnets are used to make electric motors and generators.Some magnets are used for car doors,door hinges,computers,hovers,blenders, CD players,washing machines, fax machines, escalators, elevalators,loud speakers,credit cards,tv,fridge doors,toys,jewelry, and elecric toothbrushes, magnets are used in junk yards to make new cars too,magnets are used in roller coasters.These are called electro magnets and you can turn them on and off.and they are also used in the new unistation 360 witch is awesome.
Can magnets lift up things?
Magnets are better used in lifting hot metals. Lifting magnets are the type of magnets that are used to lift high temperature magnetic materials.
Do microphones have magnets?
Some types of microphones, like dynamic microphones, contain magnets. The magnets are typically used in the mechanism that converts sound waves into electrical signals. Other microphones, such as condenser microphones, do not use magnets in their design.
Does a TV have a magnet?
Televisions with cathode ray tubes have several strong magnets in them. The magnets are used to aim the electrons that excite the phosphorus on the inside of the CRT. Flat screen TVs do not have magnets in them.
Do televisions use magnets?
Not so much with modern TVs; cathode ray tubes used powerful magnets to focus the electron stream. Modern LCD and Plasma TVs don't use magnets. Some televisions do use magnets, It just depends on which one. :D
Do the magnets in a television make the picture?
No. Or rather, it's a lot more complicated than that. Magnets are important in a cathode ray tube style television, but they don't "make the picture". The picture shows up as a result of an electron beam hitting the phosphor-covered inside of the tube. The magnets are used to steer the electron beam. In an LCD or LED type television, there are no magnets and an entirely different process is used.
What are Lanthanoid elements are used to make?
They are used to make magnets, ceramics, and television picture tubes.
Do TVs have magnets in it?
Yes, some TVs do contain magnets in the form of speakers, which use electromagnets to produce sound. Additionally, older cathode ray tube (CRT) TVs used magnets to adjust the electron beam for proper image display. However, newer flat-screen TVs like LED or LCD typically do not have magnets.
Do a television includes magnets?
Modern flat panel TVs do not, but they were used in old CRT type televisions.
How is an electromagnet used in a tv?
Magnets direct charged particles based on their mass and charge.
How can magnets be used for playing?
Magnets can be used for playing by creating magnetic games and puzzles, such as magnetic building sets, magnetic dartboards, and magnetic fishing games. Magnets can also be used in magic tricks and science experiments for entertainment and learning.
Do television has magnets?
Some older televisions had cathode-ray tubes that used electromagnets to direct the electron beam, but most modern televisions use LCD or OLED technology which do not utilize magnets. However, some televisions may have small magnets in speakers or for certain functions like attaching a remote control to the TV.
Do stereo sets have magnets?
The speakers in a stereo contain powerful magnets.
What would you use magnets for at home?
fridge magnets speakers tv
Do televisions have magnets in them?
Yes, at least in the speakers. Some older televisions used them to help direct the electron beam, though mostly electromagnets were used for that.
