Let’s get on to some physics and its mechanisms. It’s said that recently Physicists have discovered that heating one side of a magnetized nickel-iron rod results the electrons to rearrange themselves according to their spins. This concept is called as “spin Seebeck effect” leading batteries generate magnetic currents, rather than electric currents.

Here, the advantage of magnetic currents is its uses in development of spintronics devices, which use magnetic currents to reduce overheating in computer chips. Unlike electric currents, magnetic currents don’t generate heat. Guess what? Magnetic information storage is much better than storing information electronically because there is no wastage of heat. Unlike electrons that constantly bump into each other, flipping electron spins works remarkably without generating heat. It works economically by reducing the wastage of heat and leading to computer chip miniaturization, and lower power consumption along with faster operational speeds.

Lastly, spin seebeck effect passes pure spin current, a flow of electron spins without electric currents, over a long distance and will also lead to further research and wonders.
