WebA flux of magnetism—what scientists call “spins”—creates a type of energy called magnon-drag thermoelectricity, something that, until this discovery, could not be used to collect energy at room temperature. “The conventional wisdom was once that, if you have a paramagnet and you heat it up, nothing happens,” Heremans said. WebEach thermocouple is formed from two wires of different metals (or other materials). A temperature gradient along the length of each wire produces a voltage gradient from one end of the wire to the other; but the different materials produce different voltages per degree of temperature difference. garmin vhf 115 radio w/ antenna
