Step 2: Making the weaker magnet...

Now to make the weak magnet (it's unable to lift anything, but you can see that the magnetic field is there by using the compass. See the attached video).

1. Take the piece of steel off of the flame and, using the compass, point one end north and the other south.

2. Now hammer away while keeping the steel in that position. Hammer until the metal is cool.

Now you should have a weak permanent magnet.
Actually... this isn't a bad instructable. <br /> <br /> If you want to make a stronger permanent magnet you should induce an electrical field around the fork while it cools. <br /> <br /> Part of what causes a magnet is the electron vectors in the iron atoms. The more vectors that are aligned in the solid metal structure, the stronger the magnet will be. <br /> <br /> Heating the fork allows the iron atoms to come into alignment. if you 'stroke'&nbsp;it while it cools, more electron vectors will be aligned correctly. This works especially well if you have some way of rapidly cooling the fork.
<p>From what I understand from blacksmiths, the iron becomes magnetic by heating it to looses the atoms while the entire thing is under a magnetic field, then after the atoms are sufficiently lined up, and you are satisfied with it's strength, you quench it, thus freezing the metal in this lined up state. I imagine a wide coil of copper wire and a lawn mower battery could be set up, the fork heated, and with tongs, slipped into the coil and thus the magnetic field for a moment, quench, repeat.</p>
Is it important to hammer it while it cools down, what if I don't? Will it still become a permanent magnet?
its amazing ill try this @home i think its gona really strengthen my magnet<br>
could you use a electromagnet?
i use another way to do it, involves microwaves and hdds, i wi post an instructable about it in sumer
Nice.I tried using loads of super strong rare earth magnets to charge up my scissors and now it is a strong rare household magnet.
by saying that you are using napalm i assume that you are using the styrofoam/gasoline mixture? if not, please tell me what it is and how to make it
&quot;So I tried it using the napalm as my fuel source ( <a href="http://www.instructables.com/id/EL4U3X42BHERIE32Y7/">http://www.instructables.com/id/EL4U3X42BHERIE32Y7/</a> )&quot;<br/><br/>- Click on the link...<br/><br/>
Great one..<br/><br/><em>could make a magnet just by using the earth's magnetic field</em><br/>i bet lots of people never knew that (myself included)<br/><br/>from the wiki article, thinking of attaching a neodymium to a motor, and let it stroke a ferrous metal overnight..wonders if will it work..<br/><br/>
Try it and let us know :)
Wow. That's interesting.
I know. Not the most amazing thing though :( But I never knew that you could make a magnet just by using the earth's magnetic field, as weak as it turned out. So I tried it and it worked. My stronger permanent magnet (I turned my weak one into the strong one) is still able to pick up the nail.
