Can a magnet mess up a tv?
Answer Probably you can't. If the phosphor coating on the inside of the screen has been damaged, there is no way to repair it. A Cathode Ray Tube (CRT) is a sealed glass tube which is evacuated, which means that there is vacuum inside. There is no way to open the tube without breaking it. Answer You'll need a "degaussing" coil. Basically it's a large magnet that you move around the front of the picture tube, and slowly move away from it. The procedure is simple, but without a good degaussing coil you can't really fix it. The above comments, of course, only apply to older CRT-type TVs. Modern LCD screens are not affected by magnets and do not suffer from "phosphor burn".
How does the voice coil interacts with the magnet on the very bottom of the speaker?
The magnet is permanent, and the voice coil magnetism alternates with the current, pushing the cone outward against the magnet or pulling it inward towards the magnet as the current changes direction.
Which magnet is the strongest?
The strongest magnet contains neodymium a rare earth metal with atomic number of 60.
What is Sudbrook Magnet Middle School's motto?
The motto of Sudbrook Magnet Middle School is 'Committed to Excellence'.
If a bar of copper is brought near a magnet the copper bar will be what?
If a bar of copper is brought near a magnet and rubbed it will get magnetized and would behave like magnet. But this would be temporary and this property would wear after some days.
What are the property of a magnet?
A magnet possess the four properties:-attractive property-directive property-like poles repel and unlike poles attract-poles always exists in pairsattractive property: if you bring a magnet near iron filings, the iron filing will get attracted to the magnet. this is the attractive property.directive property:if a magnet is freely suspended by a thread, it will align itself in the north-south direction. this is called the directive property.like poles repel and unlike poles attract: a bar magnet's north pole is brought near the north pole of another magnet, it is observed that the the two magnets get repelled. if the same north pole is brought near the south pole of another magnet, the two magnets get attracted.poles always exists in pairs: when a magnet is cut into pieces, it will always have two poles, that is , north and south. even the smallest magnets will have this property. it is called the dipole property.
What is the attractive property of magnet?
magnets attract iron,nickel,cobalt and unlike poles towards itself , this property of magnet is known as attractive property of magnet .
What is the modern-day name for cathode rays?
I dunno if I'm right but I think it is called electrons. I mean, electrons were in cathode Rays and were bent by a magnet right?
What happens to the path of the cathode ray when the orientation of the magnet is reversed?
If the beam is bent upwards by the action of the magnet it will be bent downwards if the magnet pole is reversed and applied in the same place as before.
What happens when peice of plastic is brought near the magnet?
When some pieces of plastics are brought near the magnet, they will get attracted.

How did William crooks know that the glow in the cathode-ray tube resulted from stream of charge particles?
it was deflected by a magnet
Where does a compass point when it is moved close to a magnet?
That depends on which pole of the magnet it is moved close to. If it is brought close to the "South" pole of the magnet, the "North" pointer of the compass will be attracted to the magnet. If it is brought close to the "North" pole of the magnet, the "North" pointer of the compass will be repelled and will point AWAY from the magnet, while the "South" end of the compass pointer will point to the magnet.
What is a superconducting magnet?
A superconducting magnet is one that is made of material that exhibits the property of superconductivity.
What observations did Thomson make to suggest that an electron has negative electric charge?
Thomson observed that a cathode ray bent when in the presence of a magnetic field. After the cathode ray bent the opposite way when the opposite pole of the magnet was placed next to it, Thomson concluded that the cathode ray had a negative charge.
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.
