I think you mean "cross". And furthermore I think you mean the old iron filings around a bar magnet demonstration showing "magnetic lines of force". With all this guessing I propose an answer that your teacher won't like either: They don't cross because they don't exist. To prove this-- Sprinkle the iron filings on paper with a magnet beolw the sheet. Notice that they don't move. Photograph it. Do the experiment again. Photgraph this too and compare the two photos. They will be quite different showing that the "lines of force" are only an artifact of iron filings being sprinkled onto the paper.

Is it true that the lines of latitude called meridians never touch?
Not quite. Lines of latitude are called parallels, and they never touch each other. The meridians are lines of longitude, and all of them converge at the poles.
does magnetic field lines cross?
Never
Are white lines never broken?
Yes they are broken.
Why magnetic field lines emerge perpendicularly from the surface of permanent magnet?
This is somewhat to similar to the ejection of electrons right perpendicular to the surface of cathode. This is due to repulsion between the like charged electrons. Same way magnetic lines of force never intersect and as they repel themselves they come out perpendicularly from the surface.
A force that attracts and never repels?
Gravity!
What are three facts about electric field lines?
1. Electric field lines of force originate from the positive charge and terminate at the negative charge. 2. Electric field lines of force can never intersect each other. 3. Electric field lines of force are not present inside the conductor, it is because electric field inside the conductor is always zero. 4. Electric field lines of force are always perpendicular to the surface of conductor. 5. Curved electric field lines are always non-uniform in nature.
Can electric field lines evercross?
no, never.

Why magnetic lines of force never intersect?
ty
Why 2 magnetic fields cannot cross each other?
the tangent at any point on an electric field line gives the direction of the field at that point . so if field lines intersect then electric field at will have more than1 direction which is impossible
What are the following correctly describe electric field lines?
If we place a charged body to a position it feel a force which depends the presence of other charged body around it. Now we can say something was there in that position before placing that charged body. Here arise a concept of electric field.Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge. A simple isolated electron in an earth can create an electric field in the moon eventhough its negligible.
What are some examples of characteristics of parallel lines?
well its simple youngster, parallel lines never touch i learned that in the air force
Why do birds never get a shock when they stand on electric wire please answer in Tamil?
They do. but it you probably see them standing on phone land lines
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.
What are lines that never crossed called?
Parallel lines are lines that never cross.
Why can contour lines never intersect?
Perhaps we should start by suggesting that there really are no "lines" in an electric field (or in a magnetic field, for that matter). The "lines of force" are a convention that allows us to visualize the field. But if there were lines, they would not cross because each one is a line of force in the field, and force is affected by other force in a way that prevents the lines from crossing. The force of one line will "push off" the force of another line, and the two will "avoid" each other.Though the lines may not be real, the force of the field is real. This "arms" each line of force with "energy" to "situate" itself relative to other lines of force. The lines of force all "conspire" or "work together" to give a "net effect" to the field; the field is formed as a direct result of the "sum" of the "individual act" of each line. But they do not "cross" each other to do this. Which is pretty amazing since individual lines don't exist.We've arrived back where we started, or so it might seem. But the lines of force, though they may not exist, are part of a real field of force about the electrified object. They interact as forces (because they are each an individual expression of the field) and will not be able to interfere with one another. As a parting shot, consider that the lines of force might follow the basic tendency of things in nature to assume their lowest energy level, and will see "crossing" as requiring extra energy. They (the lines of force) simply want to "snuggle up" along side each other to create the field.
