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.

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.
How do you generate electricity using magnets to power Christmas lights?
Magnets are used to generate electricity by rotating them around a metal wire. Alternatively, rotate magnets within a coiled metal wire.
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
What are Lanthanoid elements are used to make?
They are used to make magnets, ceramics, and television picture tubes.
What are some common magnets that are found in your house?
Magnets are found in the speakers of TVs, Hi Fi systems and computers. Magnets are also often used as closure devices on bathroom cupboards & fridges.
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.
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.
Do stereo sets have magnets?
The speakers in a stereo contain powerful magnets.
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.
What would you use magnets for at home?
