| what is the phenomenon of thermoelectric effect in ferromagnetic materials |
| Answer |
Physicists discovered that heating one side of a magnetized nickel-iron rod causes electrons to rearrange themselves according to their spins. This is the so-called \"spin Seebeck effect\".It could lead to batteries that generate magnetic currents, rather than electric currents. A source of magnetic currents could be especially useful for the development of spintronics devices, which use magnetic currents in order to reduce overheating in computer chips, since, unlike electric currents, steady magnetic currents do not generate heat , but constantly changing magnetic fields that generate heat within ferromagnetic materials through electromagnetic induction. |
