That is called a magnetic compass.

Of True North and Magnetic North and Compass North which way is really up?
True North is the real North, following along the lines of longitude which converge at the North Pole, the farthest geographically North point on the planet, and the rotational axis of the planet. Magnetic North and Compass North are both the same thing, with the compass pointing along Magnetic North. Magnetic North however, is not the real North. If you were to follow your compass as far North as it could point, you would end up on the Prince of Wales Island in the Northwest Territories of Canada, over 1,500 miles away from the North Pole. Magnetic North can be adjusted to True North on your compass by knowing the local magnetic variation of your area and adding/subtracting accordingly. A third North is Grid North, which follows the Grid Lines on a standard map. At the South Pole, every direction is True North, so Grid North is used instead and can be found by following the Prime Meridian northwards. Hope that helps.
Why does south pole of the compass always point to the north while north pole always points to the south?
Like magnetic poles repel, unlike magnetic poles attract. So the magnetic south and magnetic north of two bar magnets will attract. Therefore, though the compass needle points towards the magnetic north, it is actually the magnetic south pole of the compass needle that is pointing towards the magnetic north.
How does the Earths magnetism help us find your way?
As such till now there is no proper or valid theory to prove or explain the cause of earth's magnetic field. A bar magnet or a magnetic compass alligns itself in the direction of earth's magnetic field. This process happens as south pole of magnet alligns itself to north pole of earth n vice versa true north pole is southpole of magnet. Exact location of places can be done by calculating the magnetic flux density n various other factor . . . . . .
Why is the earth magnetic full detail?
The earth has a magnetic field which is similar to a magnetic bar tilted 11 degrees. This is caused because of the North and South pole.
What direction does a compass always point?
Magnetic northNorth.In line with the earth's magnetic field.A way to remember the four directions on a compass is Never Eat Soggy Waffles or Never Eat Slimy Worms.magnetic north
A device that uses the Earths magnetic field to indicate witch way north is?
A compass.
How is the objects lifted in magnetic levitation?
It is done with a device that harnesses the earths magnetic field and separates the individual north pole and individual south pole magnets. You can read about it at GOD BASED MAGNETISM.
Switch in direction of earths magnetic north and south poles?
Magnetic Reversal
Does gps indicate true north or magnetic north?
True North
Why do scientists think that earths' magnetic field has not always pointed north?
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
What point does North America end?
At earths magnetic feild .
Where does the earths axis of rotation intersect with the earths surface?
The geographical North and South Pole - not the magnetic poles.
Can the earths magnetic field move?
Yes it can reverse from North to South
What is the switch in directions of earths magnetic north and south pole?
idontknow
Is the magnetic pole near the Earths true North Pole a magnetic south pole or a magnetic north pole?
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
How is the earths magnetic field used for navigation?
Compasses use the magnetic field to navigate always pointing North.
Do earths magnetic poles stay where they are?
No, they move slowly. The North Magnetic Pole, for example, is currently drifting a little west of north at about 40 km/year.
