What happens if the earth loses its magnetic field?Įarth’s magnetic field acts as a shield to our planet. The imaginary line of force emerging magnetic field of the earth is called magnetic field lines of the earth. This convectional current generates the magnetic field that emerges from the earth’s core out of space. When the iron and nickel core is cooled and crystallized, it rotates around the liquid core generating the electric current called a convectional current. The solidification of liquid iron and nickel in the earth’s core is responsible for the magnetic field of the earth. Among them, iron and nickel are empowered to the magnetic field lines of the earth. Our earth contains lots of minerals in its core. Frequently Asked Questions Why does the earth have magnetic field lines? Hence magnetic field lines of the earth are at their strongest at the poles. Thus, we receive maximum field lines entering and leaving the earth’s core at the poles. The flux spreads out in space from the earth’s surface. The magnetic flux specifies how tightly the magnetic field lines are packed together. The reason behind the strongest magnetic field lines at the poles is that magnetic flux. Thus at the poles of the earth, the density of magnetic field lines of the earth is more, and hence it is at its strongest. The field strength begins to minimize as the fields are far apart from the poles and near the equator. Generally, the density of the magnetic field at any point corresponds to the magnetic field at that point.Īt both poles of the earth, i.e., the north and south poles, the force of magnetic fields is strong. The location at which the magnetic field lines of the earth will be strong is based on the density of the magnetic field lines. Where is the earth’s magnetic field lines at its strongest? The angle of inclination of the magnetic field lines of the earth varies with the latitude. In the north pole, the inclination is +90°which is a vertically downward direction, and in the southern hemisphere, it is -90°, which is a vertically upward direction. In the equator, the angle of inclination of the magnetic field lines is 0°. The angle of inclination of magnetic field lines ranges from 0-90°. The magnetic field lines intersect at the surface of the earth. The field lines enter the south pole from the core and leave at the north pole. The magnetic field lines of the earth are associated with the orientation of the poles, not on geographical direction thus, the magnetic field lines of earth are in an upward direction. The motion of the convection current is always vertically upwards. Since the earth’s magnetic field is due to convection current, the direction of the magnetic field lines of the earth depends on the direction of the conventional current. The magnetic field lines of earth create the loop at the center of the earth.Unlike bar magnets, the magnetic field lines of earth are asymmetric with respect to the magnetic axis.The magnetic field lines of earth can trap the charged particles thus, the earth’s magnetosphere is formed.The magnetic field lines of earth never intersect one another while traveling between two poles of the earth.Properties of magnetic field lines of earth This magnetic field consists of imaginary lines that emerge out of the core and, travel in space, reenter the earth’s core called magnetic field lines of the earth.

The motion of the convectional current of the earth thus creates the magnetic field at the outer core. The mixture of these molten iron and nickel produces an electric current this is due to the mixture tends to generate heat that tries to escape from the core creating the current called convection current. The earth’s outer core contains molten iron and nickel. The magnetic field of the earth creates the field lines at the surface of the earth. The magnetic field lines of earth are imaginary magnetic field lines radiating from the southern half of the earth and reentering the earth at the northern half. The magnetic field produces the imaginary line of the force around the field. We know that our earth is assumed as a magnet that has magnetic fields in it.
