Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: lighters that spark when you press a switch, microphones, sensors, motors and all kinds of other devices. Now, a group of physicists has found a material with a similar property, but for magnetism. This "piezomagnetic" material changes its magnetic properties when put under mechanical strain.
