Wireless Device Unleashes Magnetism in Non-Magnetic Materials
Researchers have developed a wireless device that can induce and control magnetism in non-magnetic materials using voltage. By applying electrical voltage to a thin layer of cobalt nitride in a liquid with ionic conductivity, the researchers were able to generate an induced electric field that caused magnetism to appear in the sample. This breakthrough could have applications in fields such as biomedicine and wireless computing, enabling the control of magnetic properties in nanorobots and magnetic memories without the need for wiring. The methodology can potentially be applied to other materials and physical properties, expanding the scope of its technological impact.
