Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used; for example, lighters that spark when a switch is pressed, microphones, sensors, and motors. A material has been developed with a similar property, but for magnetism. This “piezomagnetic” material changes its magnetic properties when put under mechanical strain.
