Lodestone is an example of a natural magnet.

the magnet attracts to iron by the magnetic field both the iron and the magnet have
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.
Lodestone is the only example of a natural 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.
Why yes! Lodestone is magnetic! Lodestone is a form of iron. : )
Natural magnets are from lodestone (magnetite).
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.
It is made lodestone
Lodestone is a magnetized piece of magnetite and is sometimes referred to as magnetite. Lodestone is a naturally occurring magnet that attracts iron.
A load stone is a natrual magnet
A magnet or lodestone will do that.
The magnetic rock lodestone was found in Magnesia, Anatolia. This is how the word 'magnet' was thought to have been created.
