Fill the container about half full of water. Float a leaf on the surface of the water,
and float the needle on the leaf. That'll be a beautiful demonstration. I think I'll
make one, and I thank you for the idea.
There are a few different kinds of compass. To make a compass that makes circles you could use a pencil and tie it to another pencil and trace circles.
I'm not sure, but I can tell you that I have a very cheap (97 cent) compass that suddenly started reading backwards. I fixed it by placing it directly on top of a magnetizer-demagnetizer for several seconds (like one you use to temporarily magnetize screwdrivers with) and now it reads normal again. *I only used that tool because that's the only real magnet that I have lying around. A regular magnet may have worked as well.
Get a decent size magnet. Get some iron filaments and sprinkle the iron filaments around the magnet. You will see the magnetic field of the magnet from the iron filaments lining up from each pole and curving outwards.
by keeping another magnet or attractive force

I guess the easiest way to make it turn quite freely is to can hang it from a string.
To make a compass face the wrong way, you can do so by placing a strong magnet next to the compass needle. The magnetic force of the magnet will overpower the Earth's magnetic field, causing the compass needle to point in the opposite direction. Remember that this can temporarily disrupt the accuracy of the compass.

you cant really because the magnet in the compass controls and direct it the way it needs to go
To make a simple galvanoscope, you would need a horseshoe magnet, a thin wire, a small compass needle, and a stand. The wire is wound around the magnet, and the compass needle is suspended in the coil of wire. When an electric current flows through the wire, it creates a magnetic field that deflects the compass needle, allowing you to visualize the current.

you can make 27 out of it
To identify the north pole of a magnet, make a compass out of it by hanging it on a string or floating it on water. The pole that faces geographic north is the north pole. Once you have a magnets poles labelled, you can use it to identify orientation and poles on another magnet since like poles repel and opposite poles attract.Alternative AnswerEasier still, use a compass! A compass always points to the south magnetic pole of a magnet.
Halv that given number,Make a square that has that half number as the length of a side.Stretch the string across the diagonal of the square from corner to corner.The length of the string is the square root of the given number
