Playing with magnet..

oke guys,
now, I want to give you a game..
in here, we need :
1. steel needle
2. sewing thread 30 cm,
3. tissue
4. bar magnet, and
5. scissors

we must do :
1. Cut tissue paper and create a wing length of about 2.5 cm
2. Stick a needle through the middle of the wing to make the paper "airplane".
3. Tie a piece of yarn on the needle.
4. Put a magnet on the table with the tip protruding beyond the sides of the magnet on the table.
5. Attach the aircraft at the end of the magnet.
6. Pull the thread slowly, until the plane flying through the air.

and the result is the airplane, still flying in the air if still near to magnet.

why it can be happened?

The strength of the attraction between the two magnets depends on how regularity "magnetic force" (a group of atoms that act like tiny atoms) in the second magnet. Before affixed to a magnet, the atoms are not arranged in a regular needle. The number of atoms that arrange themselves into groups and marched in the needle during needle attached depends on the strength of the magnet.
Both needles and magnets have magnetic properties. Their attraction to the style that is large enough to overcome the downward pull by gravity, which allows the aircraft to fly fixed float.

ok friends..
happy try it..
