What force causes the needle in compass to point north earth gravity or earth magnetism?

It is the magnetism, or magnetic force, of the Earth's magnetic field.
Created by the movement of the planet's iron core, the magnetic field consists of roughly parallel lines connecting the North and South Magnetic Poles, which are not the same locations as the geographic poles. The magnetized compass needle (actually a very thin bar magnet) reacts to this field by lining up along a north-south axis.The north end of the needle indicates the direction to the North Magnetic Pole, allowing users to orient themselves directionally.

How do you show that electric current causes magnetism?
Put a wire carrying an electric current near a compass and it causes the needle to deflect.
How did Oersted discover the relationship between an electricity and magnetism?
He used an electric current to affect the needle of a compass.
Which property of a magnet is the reason why a magnet is used in a compass?
Its magnetism and the fact that the magnetism is the biggest force acting on the needle on the XY plane. This force is bigger than the friction from the spindle and the force of inertia. (The force of gravity is bigger but this acts on the Z plane) As the magnetism is the biggest force acting on the alignment of the needle it means it wants to align itself with the earths magnetic field. The result is a needle that points to magnetic north
How will you distinguish magnets from non magnetized magnetic materials?
You can use a device that detects magnetism. A compass needle may suffice.
Who is known for his research in electricity and magnetism?
Hans Christian Oersted. In 1820, he discovered that an electric current could affect a compass needle.
What does force on a magnetic compass needle represent?
magnetism
How do you show that electric current causes magnetism?

Why a compass needle not point to the geographic north pole?
maby the compass has lost its magnetism or you ar close to metal or a magnent
How did Oersted discover the relationship between an electricity and magnetism?
He used an electric current to affect the needle of a compass.
Why should you handle a compass carefully?
Since the needle in a compass is magnetized by induction it loses its magnetism easily by rough contact or heat.
Where will a compass point if you face south?
If you point the north side of the compass away from you the compass will point south. Because the needle always points north (magnetism).

Infer what characteristic of a compass needle accounts for your observation of the compass and the magnet?
because the gravity of the earth
What cause deviation in a magnetic compass?
The compass needle will only align itself with the magnetic meridian if it is free from all other influences except the magnetic field of earth.This is rarely so, particularly on a ship which constructed on steel. The magnetism induced in the steel by the earths magnetic field causes the compass needle to deviate from the magnetic meridian, by an amount which is called the DEVIATION.
