is necessary for an electric bulb to work.

Magnesium is a light metal that is not very strong. It is also not a good conductor of electricity.

Iron is a strong metal, but it is not very good at conducting electricity. It is also not as heat-resistant as tungsten.

Nichrome is a nickel-chromium alloy that is a good conductor of electricity. It is also heat-resistant, but not as much as tungsten.

Tungsten is the best material for the filament of an electric bulb because it is strong, heat-resistant, and a good conductor of electricity.
