What does the relative density of lines of a magnetic field tell us about the strength of the field?
The relative density of lines in a magnetic field diagram indicates the strength of the magnetic field in that region. A higher density of lines represents a stronger magnetic field, while a lower density indicates a weaker field. The spacing between the lines also gives an idea of the field's intensity, with closer lines indicating stronger magnetic force.
What is the importance of the inner core?
Oh, dude, the inner core is like the heart of the Earth, keeping things in check with its solid iron and nickel goodness. It's all about that magnetic field, creating a force field around our planet and protecting us from harmful solar radiation. So yeah, the inner core is pretty important if you're into living on a habitable Earth and not getting fried by cosmic rays.
Is a part of the earth that is made mostly of the metals iron and nickels?
The part of the Earth that is mostly composed of iron and nickel is the core. The core is divided into two parts: the inner core, which is solid, and the outer core, which is liquid. The presence of iron and nickel in the core gives Earth its magnetic field.
What is the procedure to draw magnetic field lines?
If it is a small magnet, like one that you can hold in your hand, place the magnet on a flat surface, put a white sheet of paper over it, take iron shavings or shavings from a magnetic metal, and sprinkle them on the paper. Gently shake the paper if you have to. You should start to see lines from where the magnetic fields attracted the metal.
Why do the earth have a magnetic field?
The Earth's magnetic field is generated by the movement of liquid iron in the outer core of the planet. This movement creates a dynamo effect that generates a magnetic field around the Earth, which helps protect the planet from solar wind and cosmic radiation.
Where does the magnetic force come from within the earth?
The magnetic force within the Earth comes from the movement of molten iron and nickel in the outer core. This movement generates electric currents, which in turn create a magnetic field. This magnetic field is what gives the Earth its north and south magnetic poles.
What gives rise to the Earths magnetic field?
The Earth's magnetic field is generated by the movement of molten iron in the outer core, driven by heat from radioactive decay and the cooling of the planet. This movement creates electric currents, which in turn produce a magnetic field around the Earth.
Do force-field exist?
Yes. There is only one problem. Its just that it is 1cm cubed. Very tiny. And obviously, the mathematical one which gives of a magnetic force field exists.
What metal lies inside the Earth's core which gives the Earth its magnetic field?
The Earth's magnetic field is the result of electric currents in the liquid metal outer core.The outer core of the Earth is over 2,000 km thick. It sits above the solid inner core and is composed of highly conducting liquid iron and nickel. Above the outer core is the Earth's mantle.The geodynamo is the mechanism thought to be responsible for the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field.See related links.

How does a magnet exerts force?
Well its all about arrangement of electrons inside the metal. This arrangement gives rise to a force field(not a shield used by the invisible woman in the fantastic four) which has the property of attracting small pieces of iron fillings. Or it may produce electricity when it is displaced around a conductor. How the field arises is the same as how electric force arises.
Earth revoles on its axis true or false?
Yes, it does though it wobbles a bit. This gives us seasons and the magnetic field that a compass detects.
What is the force exerted on objects by the earths pull?
There is both gravitational and magnetic force associated with the earth. The mass of the earth gives rise to gravity, and magneto action in the core generates the magnetic field that moves compass needles.
What is belived to be responsible for the earth's magnetic field?
The earth's magnetic field arises from the core of the earth(that we know) but why? Have you ever heard of lodestones? Well they are naturally occurring magnets. They are basically composed of ferromagnetic materials like iron. Their magnetic property arises because the iron stays aligned with the magnetic field lines of the earth leading to a change in the arrangement of their electrons. But our discussion is for the origin of earth's magnetism. Well the core of the earth is composed of materials like Nickel and Iron, hence the core is sometimes called NiFe. Due to hot temperatures and pressure the electrons in the core are constantly changing positions and hence giving out a magnetic flux. The flux density is what gives the field.
What part of an object is a measure of the force of gravity between earth and the object?
The object has mass, and the force of gravity gives that object weight, which is mass in a gravimetric field.
Does the earth act like a big bar magnet?
The earth acts as a sort of magnet. The gravity is like a + and we are - but neither of us have any charge, unlike magnets. The gravity has a downward force on mass (which is always constant) and gives us 'weight'. Weight is not a constant and changes as gravity increases or decreases. Magnets do not effect weight.
A loop of wire is placed in a uniform magnetic field.In which orientation of the loop is the magnetic flux linked with it maximum?
1. The orientation giving the maximum magnetic flux would be 90 degrees or perpendicular to the magnetic field because that gives the maximum amount of magnetic field lines able to pass through the area of the coil. The greater density of field lines gives a greater magnetic field. The orientation that would give a magnetic flux of zero is the plane of the coil to be parallel to the magnetic field, making no lines pass through the coil and thus no flux.
