The reason i have this question is because when i put a glass ashtray in front my TV without a using it at all. There is an area of the TV screen that has a tint variation only were tha ashtray is sitting. I am wondering if it can hold remnance of a magnetic field because a recently used the ashtray to hold a rare earth magnet for an expeirament and recently have noticed this anomaly. Because i've had the understanding that glass has no magnetic properties.
It appears that it is, altough I would prefer additional confirmation. I took a cookie sheet, filled it with 8mm of water, floated an 8 x 8 cm piece of styrofoam on it and put a small empty glass vial on the styrofoam's center. I then took a rare earth magnet (from a computer hard drive) and was able to push the raft around by imparting the magnetic field on the glass vial. Care was taken to reduce air currents and other factors. The effect was small but easily observable... iif you are patient.
No it doesn't.
no
yes
no, glass isn't magnetic
One form of magnetic glass is a painted glass that is laminated to steel. This gives the glass a magnetic white board effect. Because any magnet used must be strong enough to reach the steel through the glass this generally only works with strong magnets like rare earth magnets.

I don't think magnetism is affected by glass. Edit: Magnetic field are unaffected by glass. Magnets and electrical fields in general are only effected by other magnetic fields and materials which generate them. Think of a compass that is brought near another magnet. Magnetic fields are exponential in strength meaning that they are most strong at the surface and quickly fade with distance. Dont remember the equation but its simple and straight forward. So if you want a magnetic field to extend through a thick (5mmm) piece of glass you will need larger more powerful magnets such as rare earth or neodymium magnets. Its really about the strength of the magnet and the distance of the magnetic field. Hope that helps.
Electrostatic or magnetic charges ? the answers are different.If electrostatic charges, I GUESS that an antistatic-coated glass plate would not affect the charges at all.If it were left to accumulate charge, an insulating glass plate placed between the two charges would assume a potential between that of the two bodies. [Assuming it were free to accumulate a charge.]If magnetic charges, the glass plate would have no effect. [But the 'glass plate' equivalent would be a soft iron sheet, or a wire mesh screen of soft iron. ...Continue with your analysis of the analogy.
Most forms of glass do not change the speed of light. Darker glass lets less light through it Glass at an angle to light may refract ( bend) light or glass may break light up into all the colours the light is made of rainbow / spectrum. The only way anyone has successfully stopped and restarted light is using magnetic beams

A marble with a magnetic
It depends on how thick the glass is and how strong the magnets are.
Magnetic Glass Write Boards can be purchased in a variety of colors and sizes from HighTower Group. They have a good website that includes an online video overview: In addition to magnetic glass they also sell all of the accessories like white dry erase markers, magnetic erasers and rare earth magnets
Magnetic materials: -steel -iron -nickel -cobalt Non-magnetic materials: -aluminum -copper -zinc -gold -silver -wood -plastic -glass Note: Not all forms of Iron are magnetic.
One possible way to separate wooden marbles from glass marbles is by using a magnetic field. Since wooden marbles are typically not magnetic, while glass marbles are also not magnetic, one can use a strong magnet to attract and separate the wooden marbles from the glass marbles. The magnet will attract the wooden marbles while the glass marbles will remain unaffected and can be easily sorted out.
Not if it is a glass marble, but you can get metal marbles which would be magnetic in many cases.
magnets cant find glass unless the glass has iron essence in it or has been rubbed up against magnetic metal a lot.
The hard disks of computers are usually glass or aluminum coated with a very thin layer of fine grained magnetic material.
no it cant, because it will never have the abiliry to obtain magnetic properties
That statement is not true. Yes a magnet will attract a steel paper clip through air or water. No, a magnetic field will penetrate glass as well... probably. Certain types of glass (which are themselves ferromagnetic) might serve to block a magnetic field.
