Material changes from solid to liquid in response to magnetic field

 A new type of material can change from solid to liquid in response to an alternating magnetic field. The material has a wide range of potential uses, and its creators have demonstrated how it might be applied in electronic circuitry, drug delivery and for fastening objects in confined spaces. They even used it to make a Lego man capable of melting, breaking out of a prison cell and reforming in a dramatic scene reminiscent of the 1991 sci-fi classic Terminator 2.
