Researchers from the Norwegian University of Science and Technology (NTNU) and the University of Cambridge in the UK have shown that you can directly generate an electric current in a magnetic material by rotating the material's magnetization.
This new link between magnetism and electricity, called charge pumping, may find applications in spintronics devices. It will enable new nano-scale magnetic information detection techniques and can also be used to generate very high-frequency alternating currents.
