What do magnetic field lines that curve away from each other show?

The difficulty of attempting to measure something, without altering it by the attempt, is well shown in attempting to measure magnetic field lines.
First, the lines of magnetic force are an artificial construct - in the same way as many contour lines are.
Consider the 'field lines' between two poles of a magnetic. The magnetic field concerned will vary in a perfectly smooth manner as one moves away from the most central position between the two poles, to the positions most remote from the poles. There is no reason to believe that any one curve between the poles is preferred over any other; or any more real.
When we sprinkle iron filings on the region between the two poles, we alter the properties of the field in a most egregious manner.
The iron filings are ferromagnetic, and an individual filing thus concentrates the field in its region. AND the individual filing will have its own North and South pole.
These filings will form a chain of interconnected filings, each with its own N and S poles, and attracted to the N and S poles of the next filing in that line.
At the same time, the N and S poles of an individual filing will REPEL from adjacent similar fields. Thus there will appear to be lines of filings, roughly parallel to each other, and becoming closer as they approach the high intensity of the magnet's real poles.
A similar problem will occur when attempting to measure the strength of an electrostatic field. For any dust sensitive to an electrostatic field will attract surplus electrons to itself, thus distorting the image of the field.

What if a magnetic needle is kept in a non uniform magnetic field?
A magnetic needle kept in uniform magnetic field will experience zero net force but non-zero net torque........Since the magnetic lines are uniform,the force acting on each end of the needlewill be equal and opposite.So it will cancel each other resulting zero net force.
What is similar between force fields and magnetism?
Force field refers to the lines of force one object exerts on another object or a collection of other objects. Note that force fields does not exist in reality, but are really a construct that allows scientists to visualize the effects of objects on other objects; in other words, it makes the math easy. Examples of force fields: Newtonian gravitational field, global Gravitational field, A conservative Electric field, A static Magnetic field. A magnetic field is a field that permeates space and which exerts a magnetic force on moving electric charges and magnetic dipoles.
How do the iron filings behave when sprinkled over the bar or horseshoe magnet?
spread out from one pole and curve around to the other
What does magnetic field lines denotes?
a line to represent the direction of a region around a magnetic material or a moving electric charge within which the force of magnetism acts.A2. Perhaps better describes as lines of magnetic force. These are lines of equal intensity between the North and South pole of a magnet. They are similarly charged, hence they repel each other. They extend arbitrarily far into space if allowed to, and will eventually form a sphere.These lines of magnetic force are that along which your compass aligns itself at your locale.
How does magnitiom work?
A magnet is any material or object that produces a magnetic field. This magnetic field is responsible for the property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets.
What do field lines show that curve toward each other show?
It has No magnetic interaction
How are magnetic field lines arranged?
Magnetic field lines spread out from one pole, curve around the magnet, and return to the other pole.. . ah, they don't actually spread out from the poles, inside the magnet they are bunched together but they still form closed loops with the lines outside.
Magnetic field lines cross each other?
No, they don't.
What is the imaginary line that helps us visualise a electric or magnetic field called?
They are force field lines at right angles to each other as depicted in the related link.
What occurs to the magnetic field lines when the magnets have opposite poles facing each other?
The field lines are parallel and create an attractive force field.
Could a magnetic field be electrons flowing through power lines?
A magnetic field is caused by flowing currents, but the field lines are not directly related to the flow of electrons or other charged particles. They are simply an abstraction that tells you where the magnetic attraction is strongest, and in what direction it goes.
What can you use to show the magnetic field of a magnet for people to see?
Little bits of other magnet. Iron filings - the small pieces of metal will floow the magnetic field lines.
Does the gravity affect the magnetic force lines by space distortion?
Magnetic lines of force follow space. If space is distorted by the presence of a large gravitational field, the magnetic lines will be distorted as well. Other than near black holes, this effect is negligible.
Do magnetic field lines ever cross each other at any point?
Not if they come from the same source.
Do magnetic field lines come out both poles?
They start from one pole and terminate at the other end.
What do you mean by uniform and non uniform magnetic fields?
In a uniform magnetic field the imaginary magnetic lines of force are parallel to each other. But in case of non uniform they are not parallel
What is the direction of the magnetic field of a bar magnet?
The field lines would leave one pole (end of the magnet) and then curve around one side to come back to the other pole in kind of a semi-oval. Picture two ovals side by side, then picture the bar magnet placed between them, overlaying the long edges of the ovals where the ovals touch. This can be observed by pouring some iron filings onto a piece of paper and then placing a bar magnet underneath the paper. The filings will line up along the field lines providing a visual picture.
