Magnetic poles exist in pairs. It is not possible to isolate a north pole or a south pole. Magnetic field lines start from the north pole and go to the south pole and return to the north pole. They form continuous closed loops unlike electric lines of force which do not as an electric monopole, a single charge does exist.

The correct statement about magnetic field lines is option 'A': The magnetic field lines of a magnet (or a solenoid) form continuous closed loops.
Explanation:
Magnetic field lines are used to visualize the direction and strength of a magnetic field. They provide a way to represent the behavior of magnetic fields in a visual and intuitive manner. Here is an explanation of each statement and why option 'A' is the correct one:
a) The magnetic field lines of a magnet (or a solenoid) form continuous closed loops:
- This statement is true. Magnetic field lines always form closed loops. They start from the north pole of a magnet, curve around the magnet, and end at the south pole. The lines never start or end in isolation.
b) The smaller the number of field lines crossing per unit area, the stronger is the magnitude of the magnetic field B:
- This statement is incorrect. The number of field lines crossing per unit area does not determine the strength of the magnetic field. The density of field lines represents the strength of the magnetic field, not the number of lines.
c) The perpendicular to the field line at a given point gives direction of magnetic field:
- This statement is true. At any given point along a magnetic field line, the direction of the line gives the direction of the magnetic field at that point. The field lines are always perpendicular to the magnetic field.
d) The larger the number of field lines crossing per unit area, the weaker is the magnitude of the magnetic field B:
- This statement is incorrect. The number of field lines crossing per unit area does not determine the magnitude or strength of the magnetic field. The density or spacing of the field lines represents the strength of the magnetic field.
In summary, option 'A' is the correct statement because magnetic field lines always form continuous closed loops, starting from the north pole and ending at the south pole of a magnet.
