Yamagata University, Japan, announced that its researchers have developed a new material that is as soft as rubber, but becomes harder in the magnetic field. This material is expected to be used to make earthquake-resistant components, automotive cushioning materials, and functional furniture that can disperse body weight. The team at Yamagata University in Japan added iron particles with a diameter of 3 μm to a polyurethane resin, and then used a permanent magnet to create a magnetic field of 300 milli- Tesla (magnetic induction unit). After 1/10 second, the iron particles were arranged in a straight line. The rubber material also becomes hard. According to the strength of the magnetic field, the hardness of this new material can reach up to 180 times the original hardness. Previous research has also been devoted to the development of similar materials, but its hardness can only reach three times the original hardness. Tests conducted by the Yamagata University research team showed that a 3.5-cm-diameter, 5-cm-high rubber cylinder made using this technique is hard enough to withstand more than 8 tons of pressure. After removing the magnetic field for tens of seconds, this material can restore its original softness.
