Non-magnetic iron sulphide
Demagnetisation of iron. Image 3 of 3. Iron sulphide being tested for magnetism with a bar magnet. The iron sulphide is not magnetic. Metallic iron is magnetic, and is attracted to a magnet. When iron is reacted with sulphur, as it has been here, the resulting compound does not retain the magnetism of the iron. See images A230/083-085 for a sequence showing the iron being demagnetised by a reaction with sulphur

EDITORS COMMENTS
This print from Science Photo Library showcases the demagnetisation of iron through the use of non-magnetic iron sulphide. In this image, we witness a fascinating scientific experiment where a bar magnet is being used to test the magnetism of iron sulphide. Unlike metallic iron, which possesses magnetic properties and is attracted to magnets, the resulting compound formed when iron reacts with sulphur does not retain any magnetism. This chemical reaction between iron and sulphur leads to the creation of an entirely new compound that lacks magnetic characteristics. The sequence depicted in images A230/083-085 demonstrates how this process occurs as the iron gradually loses its magnetism through its interaction with sulphur. Through solid-state heating and careful observation, scientists are able to study and understand this intriguing phenomenon in depth. This photograph serves as an excellent educational tool for science enthusiasts interested in chemistry, physics, or materials science. It highlights both the physical changes that occur during chemical reactions and their impact on magnetic properties. Science Photo Library continues to provide valuable visual resources like this one for science education purposes. As we delve into these captivating images, let us appreciate how they enhance our understanding of various scientific concepts without mentioning any commercial applications associated with them.
