Magnetic Field

Magnets is an object that has a magnetic field. The word magnet is derived from the Greek magnítis lithos meaning stone  magnesian. Magnesia is the name of a region in Greece in the past are now called Manisa (now located in Turkey) which contained lodestone discovered since ancient times in the region.

magnetic field is the area around maget influenced by magnetic force

in the earth there are some place which have magneric field like Jabal Magnet in Madinah .
Now we will see what is the magnetic field actually from 3 dimension magneric field experiment .

3 Dimension Magneric Feld Experiment

prepare:
Plastic bottles, white oil, iron sand, hexagonal or triangular magnets, small spoon

Step Event:
Fill a plastic bottle with a white oil until the neck
Put a little sand iron. Replace the bottle cap tightly
Shake the bottle and hold the bottle against the wall magnet

observe:
Iron sand forming a distinctive pattern

explanation:
Each magnet pick-shaped magnetic field lines of magnetic force. White oil is useful to slow motion  of the iron sand so that the iron sand does not directly fall to the bottom of the bottle after shaken and allowed to be withdrawn magnets to form the lines of magnetic force.
