Question

Choose correct option regarding magnetic lines of force.

• A. Intersect near north pole or south pole
• B. Intersect at the neutral point
• C. Never intersect each other
• D. Intersect at the mid point of the magnet

Hint:

Magnetic field lines may come very close to each other in strong magnetic regions, but they can never cross or intersect.

Answer 1

The Correct Option is C

Concept: Magnetic field lines are imaginary lines that represent the direction and strength of a magnetic field around a magnet.

Step 1: Understand the direction of magnetic field. At every point in a magnetic field, the magnetic field has only one unique direction. The tangent drawn to a magnetic field line at any point gives the direction of the magnetic field at that point.

Step 2: Consider intersection of field lines. Suppose two magnetic field lines intersect at a point. Then two tangents can be drawn at that point, giving two different directions of magnetic field at the same location. This is physically impossible because magnetic field at a point cannot have two directions simultaneously.

Step 3: State the conclusion. Therefore, magnetic field lines: \[ \boxed{\text{Never intersect each other}} \] Hence, the correct option is (3).
