Elder Futhark Runes Magnet

The Runic alphabet is also known as Futhark, a name composed from the first six letters of the alphabet, namely f, u, th, a, r, and k. In this way, "Futhark" is analogous to the word "alphabet", which is from alpha and beta, the first two letters of the Greek alphabet. And why were the letters ordered in such a way. Nobody knows the answer, but it might been some form of mneumonic function that was not preserved.
