what makes north so magnetic to attract the nidle from every where in the planet.
please explain becouse i want to understand it.

there is a layer of magnetic rock beneath the earth's crust that has a magnetic force pointing in one set direction. the needle of a compass is made of a material that reacts with this magnetic force and is pushed in the same direction as the force points

Compasses actually face both north and south, it's just a matter of which end of the needle is painted. The reason they face north-south is because the magnetic field of the earth is lined up so that the geographical north pole (up near Greenland and all that) is really close to the magnetic north pole, and south pole lined up with the south pole. All magnets have two poles, and we just call them north and south because that system of north being towards Greenland and Russia and south being the other way was already in place when we discovered magnetic poles.

The Earth is kind of like a large magnet with both a south and north pole. The earliest compasses were made by magnetizing a needle by putting it on a magnet, then putting it on cork and floating it on water. Get a magnet or two and play with the polarity. Get iron filings and play with magnets and them on each side of a piece of paper. Get a piece of steel dowel or chisel. Face it north and pound it with a hammer to magnetize it. Test it by picking up staples or something. Play with solanoids. Magnetism is very cool and fun.

The needle points to magnetic north because the Earth's poles are magnetized.

THE EARTH HAS MANETIC POLES IN ITS NORTH AND SOUTH.The compass needle is a small magnet and as the opposite poles attract ,so one side of needle gets directed to north and other to south of earth's poles due to this called magnetic pull.

So we have a standard to follow. I mean, the magnet would still be drawn North because of polarity, but I'm sure we could design something for you that would point south.

The magnetic pole is near the north pole

Compasses point to magnetic north not to be confused with true north.

They point to the Northern Magnetic Field.

They Face South West And East To.
