You can magnetize a piece of steel or iron, by stroking it with one end of a magnet.
Stroke in one direction only, lifting off and away between each stroke.
This aligns the atoms in a regular direction, in the blank piece of steel.
There are several sites that one can use to make a magnet. Websites that allow the design of cards will also show one how to make a magnet. Zazzle, Shutterfly and Vistaprint are some of these sites.
Remembering the rule that opposites attract and sames repel, you can use the South end of one magnet to repel the South end of a second magnet. If the 2 magnets are aligned vertically and the repelling force is sufficient to push the weight of the upper magnet away, you have a very basic levitation.
To make a magnet float using another magnet, you can use the principle of magnetic repulsion. By placing two magnets with like poles facing each other, the repelling force between them can create a levitating effect, causing one magnet to float above the other.
Use the magnet to stroke the iron nail many times and you try to attract something
rub against needle with strong magnet i guess 1. Hold a needle by the eye and stroke it gently 30 times with your magnet, in the same direction. Do the same with the second needle, making sure that you use the same end of the magnet. 2. Test your needle-magnets on some pins before you use them for other experiments.
To make a powerful magnet, use a strong magnetic material like neodymium. Shape it into a magnet by applying a magnetic field while it cools down. Finally, the magnet can be magnetized by rubbing it against a magnet or by exposing it to an electrical current.
No it will only be possible for it to be a temporary one
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.

One way to separate iron nails from copper tacks is to use a magnet. The iron nails will be attracted to the magnet, allowing you to easily separate them from the copper tacks.
To determine the polarity of a magnet, you can use a compass. The end of the magnet that attracts the north pole of the compass is the magnet's north pole, and the end that attracts the south pole of the compass is the magnet's south pole.
To install a magnet on a crank, you can use an adhesive or epoxy to secure the magnet to the crank arm. Make sure the surface is clean and dry before attaching the magnet. Ensure that the magnet is positioned correctly to align with the sensor for accurate readings.
