Magnet links are as close to magic as one can get.
A magnet link is basically a word. A word of power - and therefore a very long word. It is a word composed of what seems to be random numbers and letters (and a lot of them), and is therefore utterly unreadable to the naked human eye. But through the careful application of computation, these seemingly random strings of symbols can be turned into - well, just about anything, really.
That's the magic of them.
And once you know one of these words (or have it stored somewhere), you can summon up this anything whenever you want. Just utter the word in the correct setting, and the summoning begins.
It used to be a cliché that magicians utter strange, incomprehensible words and magic happened. Now, we take this for granted. Even children can accomplish these feats nowadays - and so they do, every day. Without really thinking about it.
It just goes to show that the world is full of magic.
One word is all it takes.
