Bar Magnet Field Lines Analysis

The question asks about the properties of magnetic field lines around a bar magnet. Let's analyze the given statements:

• Statement (i): The relative strength of the magnetic field is shown by the degree of closeness of the field lines.

  This statement is true. Magnetic field lines are closer together where the magnetic field is stronger and farther apart where the field is weaker. The density of the lines visually represents the field's strength.

• Statement (ii): No two magnetic field lines can intersect each other.

  This statement is also true. If two magnetic field lines were to intersect at a point, it would imply that the magnetic field has two different directions at that single point. Since the magnetic field at any point has a unique direction, field lines cannot intersect.

Both statements (i) and (ii) accurately describe the properties of magnetic field lines around a bar magnet.

Conclusion

Since both statement (i) and statement (ii) are true, the correct option is the one that includes both.
