Now I am going to show you how to see the inisible lines called magnetic field. It is very easy so let's get started.

Step 1: Step 1 : Materials

You are going to need : 3 pieces of clear plastic

some drill bits

some bolts and nuts

and some pushpin tips

Step 2: Step 2 : Making

Take one piece of plastic and mark where you want holes. Than drill them and clean the edges.

Finally screw all three pieces together but do not forget to put the tips of pushpins !

And you are done ... Enjoy !

Very cool. Have you noticed any difference in the feild shape when useing various magnets?
<p>Yes they are definitely some differences but I do not have so many magnets to show you ... so you must make it and try it on your own :)</p>
what you didn't get? this thing shows you the magnetic field... the picture is not very good.. these lines are not perfect.
I don't get it...
