Supermagnet

a super magnet, or otherwise known as a neodymium magnet, is a very strong magnet that is composed of neodymium, iron, and boron. anyway, i'm not going to bore you with the scientific facts.

i bought 40 of these magnets last year that are in the shape of spheres. i believe there are graded N35 which makes them an average super magnet. in more than one occasion they had nipped my skin but i still like it as it is.

pictures:

arranged into 4 rings and stacked on one another:

made into 4 straight lines and combined:

combination that makes it look more or less like a ball:

super magnet bracelet anyone:

in this arrangement, all the super magnetic waves interconnect to form it into a combined 'bar' of super magnet:

you can keep turning and it will never end:

so what is so special here? it seems evident that a super magnet is stronger than a regular magnet but just how strong is it? according to wiki, it could lift off about 1300 times its original weight. just to give you a feel on how big my magnets are first:
as you can see, that is a one sen coin and two of my super magnets. 1300 times its own mass still sounds like a brag initially but after i tested it, i was surprised:
if you click on the image you can see the magnet as a shiny thing between the pole and the metal objects. the hammer, chisels were as heavy as the 3 spanner combined so no cheating here. mind you, the attempt to take this picture caused these tools to drop on the floor several times.

so i thought:'if one super magnet could lift these things, then if i take 20 and split them 5 each i could lift 8 times the weight. so i put everything (and a little more) into a metal toolbox and did this:
there is actually 8 'strings' of super magnets but 1 is being blocked from sight. when i did this, i thought that the toolbox was in the verge of dropping. but when i was taking it down, i still needed to apply some force. 1300 times its own mass indeed.

so why are such powerful magnets created anyway? well, they are used in many items around us such as in a hard disk and sometimes even in hand phones.

of course, the final conclusion of the post is that something small can still pack a punch.
