An international team of scientists has demonstrated the first soap that responds to magnets. This means the soap and the materials that it dissolves can be removed easily by applying a magnetic field.
Details of the new soap, which contains iron atoms, are reported in the chemistry journal Angewandte Chemie. It is similar to ordinary soap, but the atoms of iron help form tiny particles that are easily removed magnetically.
Experts say that with further development, it could find applications in cleaning up oil spills and waste water.
