can be separated by using a magnet
It depends on the type of lamp and the strength of the magnet. An incandescent lamp works literally by running current through the filament to heat it. Parts of the bulb might be magnetic, so if the magnet were ridiculously powerful it might deform or break them. Fluorescent and Neon lamps use ionization, so although I haven't tried it, I'd bet a reasonably strong magnet might affect them. If you have an old CRT-based television or computer monitor you can see how this works by placing a magnet near it -- note, this can cause permanent effects to the picture quality, so either keep the magnet at a distance where the effect is minimal or use a CRT you don't care about. LED lamps are so small and well-constructed that I think they're more like incandescent lamps -- a really powerful magnet might damage them, but otherwise is unlikely to affect them.
the magnetic field of a magnet is measured through Gaussmeters.
A lodestone is a naturally occurring magnet and is considered to be a strong magnet.
a rock that has magnet paint on it and then it is magnetic
The natural magnet is present at the core of our planet earth.
Natural magnets are from lodestone (magnetite).
Magnetite is an example of a natural magnet. It is a type of iron ore that is naturally magnetic and can attract materials containing iron. Magnetite is commonly found in countries like Sweden, Russia, and the United States.
Magnets are made by lodestone. If the magnetic qualities of lodestone are passed in a magnetic substance, then it will be a permanent magnet.
China is one. Lodestone is the main ingredient of a magnet.
A load stone is a natrual magnet
A magnet or lodestone will do that.
A lodestone has two poles: a north pole and a south pole, similar to a regular magnet.
Yes, lodestone is a natural magnet made of magnetite ore. It is a naturally-occurring magnetic rock that can attract iron.
Another name for lodestone is magnetite. Lodestone is a naturally magnetized form of magnetite that was used in ancient times for navigation.
