Liquid oxygen is magnetic, and it can be moved around and even picked up with a powerful magnet. Oxygen is a colourless, odourless, tasteless gas composed of the simple diatomic molecule, O2. It condenses at -183°C to a pale blue liquid, that is unusual in that it is magnetic. Indeed, a magnet has the ability to pick up liquid oxygen. The gas is also magnetic, and this property can be used as a means to detect how much O2 is present in gas samples - for example in incubators for premature babies.
