Why sand is attracted to magnet even though it is not a metal?
Often, black sand is composed of magnetite, which is an ironbrimmed mineral or a form of iron oxide Its grains are very small, opaque, extremely black, and magnetic, which is why sand tends to attach to a magnet If you see other types of sand with the same behavior, chances are there are magnetic particles in its compositionMagnetic fields The region around a magnet where a force can be felt is called the magnetic field If magnetic materials enter this region, they will be attracted to the magnet PermanentMagnets and magnetic materials BBC Bitesize
