Which one of the following statements regarding magnetic field is NOT correct?

CONCEPT:

• Magnetic field and magnetic lines of force: It is the space around a magnetic pole or magnet or current-carrying wire within which it's magnetic effect can be experienced is defined as a magnetic field.

• The magnetic field can be represented with the help of a set of lines or curves called magnetic lines of force or magnetic field lines.

Properties of Magnetic Field Lines: 

1. A magnetic field line is directed from north-pole to south-pole outside the magnet.
2. A magnetic field line is a closed and continuous curve. (Magnetic field lines inside the magnet where these are directed from south pole to north pole).
3. The magnetic field lines are crowded near the pole where the magnetic field is strong and are far apart near the middle of the magnet and far from the magnet where the magnetic field is weak.
4. The magnetic field lines never intersect each other because if they do so, there would be two directions of the magnetic field at that point which is absurd.
5. In case the field lines are parallel and equidistant, these represent a uniform magnetic field. The Earth's magnetic field is uniform in a limited space. 

EXPLANATION:

• From the above, it is clear that the magnetic field line is a closed and continuous curve.
• Therefore statement 2 is correct and statement 3 is incorrect. So, option 3 is correct.
