What would happen if field lines crossed?
Then, at some point, the field would go into two directions simultaneously, which doesn't make much sense. The magnetic field lines form continuous closed loops.The tangent to the field line at a point represent the direction of the net magnetic field B,at that point.The magnetic field lines do not intersect,if they did, the direction of the magnetic field would not be unique at the point of intersection.
Do magnetic field lines ever intersect?
yes
Why do two magnetic lines never intersect each other?
It is important to realize that magnetic lines do not really exist! They are a tool to visualize the magnetic field, but the field is continuous and does not exist solely inside lines. The direction of the lines gives the direction of the magnetic field, the density of lines, its strength. This also explains why no two field lines can ever intersect; a field line carries information about the direction of the magnetic field, if they would intersect an ambiguity would arise about the direction (not to mention a field of apparent infinite strength since the density would be infinite at the point of crossing). The field lines are almost never used in explicit calculations; instead one uses a vector, an entity which contains information about the magnitude and direction of a field in every point in space and time. Adding two magnetic fields is then easy; just add the vectors of both fields in every point in space (and time). You can use the resulting vector field to draw field lines again if you want. An easy way to imagine what would happen to field lines when they might intersect is to look at them as being such vectors. Imagine you have one field line pointing to the right, and another one pointing up. The result of adding would be a field line pointing somewhere in the up-right direction (the exact direction depending on the relative magnitudes of the fields). If the fields are equal in magnitude but opposite in direction they would cancel; the field line disappears. But this is to be expected! The magnetic fields canceled each other in that point! One has to take care with this analogy however; as for field lines the measure of magnitude is their density; which is an undefined thing if you are considering just one field line per field. For a vector however, the measure of magnitude is its length. Therefore adding two field lines of the same magnitude and pointing in the same direction would result in a vector of twice the length, but in field line language you would have to double the density at that point. This is one of the reasons field lines are used for visualization but not calculation. By the way, all these things apply to other fields as well. Electric fields can also be represented by field lines, and they as well cannot intersect (for the same reasons). Electric field lines, however, are not necessarily closed loops like magnetic field lines (this has to do with the non-existence of magnetic monopoles).
Do intersecting lines ever cross?
Intersecting lines are two lines that cross in a coordinate plane. So, yes, intersecting lines cross.
What is meant by magnetic permeability?
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
Do magnetic field lines cross?
No.No.No.No.
does magnetic field lines cross?
Never
Magnetic field lines cross each other?
No, they don't.
Do magnetic field lines always cross?
Actually, they NEVER do.
Do magnetic field lines ever cross each other at any point?
No, magnetic field lines do not cross each other at any point. This is a fundamental property of magnetic fields known as the "no crossing rule". If lines were to cross, it would imply the existence of multiple directions for the magnetic field at that point, which is physically impossible.
Do magnetic field lines close together indicate a weaker magnetic field?
No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.
Which of the following correctly describe magnetic field line?
APEX: Field lines that are close together indicate a stronger magnetic field. They don't affect the magnet that created them. They never cross. They begin on north poles and end on south poles.
What correctly describes magnetic field lines?
The list of choices submitted with the question containsno correct description of magnetic field lines.
How tightly packed the magnetic lines tells us?
The density of magnetic field lines indicates the strength of the magnetic field. More closely packed lines suggest a stronger magnetic field, while widely spaced lines suggest a weaker field in that region. The direction of the magnetic field is indicated by the orientation of the field lines.
What are the lines called that map out the magnetic field around magnetic?
They are called the magnetic field lines.
What three features do magnetic field lines show?
Magnetic field lines show the direction of the magnetic field, the magnitude of the magnetic field (closeness of the lines), and the shape of the magnetic field around a magnet or current-carrying wire.
Are the lines that map out the magnetic field around a magnet?
The lines that map out the magnetic field around a magnet are called magnetic field lines. These lines indicate the direction of the magnetic field and its strength at different points around the magnet. Magnetic field lines are closest together where the magnetic field is strongest and they form closed loops that do not intersect.
