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).

What are examples of a line and a ray in the Real World?

A line in the real world would be, train tracks and a ray would be, a baseball field..........=) A line in the real world would be, train tracks and a ray would be, a baseball field..........=) Or.... a dolphin!! Don't believe me look it up

How do the electric field lines around a positive charge look?

The electric field lines around a positive charge point radially outward in all directions, indicating the direction of the electric field. The field lines are directed away from the positive charge and become less dense as they move farther away from the charge.

Draw a shape with two lines of symmetry?

A line of symmetry can be thought of as the line where you could cut a shape (or a line or any object) and it would look the exact same on both sides. An example of a shape with exactly two lines of symmetry would be a rectangle. A square also has at least two lines of symmetry, but it actually has four total.

Is football known as a gridiron sport because of its field?

Kind of. If you were to look at an American football field from above, the way the chalk lines are laid out for the yard lines and end zones would make it look something like a gridiron.

Is a baseball diamond really a diamond?

The baseball term diamond is in reference to the object you would see if you drew a line from home plate to first base, first base to second base, second base to third base, and third base to home plate. Each of these lines would be the same length (90 feet), therefore, the object would look like a square if you were sitting down the left field or right field lines. But if you were sitting in center field or behind home plate, the object would look like a diamond. A diamond is really a square turned on it's side.

What do the electric field lines look like when the electric field has the same strength at all points in a region?

When the electric field has the same strength at all points in a region, the electric field lines will be equally spaced and parallel to each other. This indicates a uniform electric field, with the field lines running from positive to negative charges in a straight path.

What does an intersecting line look like?

two lines that cross

What is an easy way to remember which way horizontal lines are drawn?

Look at a letter H. Look at the line in the middle. It is flat. The line in the middle of the letter H is like the flat horizontal line. Now, look at the letter V. The lines on the side are kind of straight, and pointing up and down. That is a vertical line.

What does an instrument hold line look like?

The instrument hold line look a little like an latter in the it is 2 pararell yellow lines seperarted by 6 to eight inches and with perpindicular line joining the two lines. think Rail road tracks

What does intersecting lines look like?

An intersecting line looks like their hugging with is crossing
