Which of the following is/are true about the magnetic field lines around a bar magnet? (i) The relative strength of the magnetic field is shown by the degree of closeness of the field lines. (ii) No two magnetic field lines can intersect each other.
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.

With reference to street-lighting, how do sodium lamps differ from LED lamps?
1. Sodium lamps produce light in 360 degrees but it is not so in the case of LED lamps.
2. As street lights, sodium lamps have a longer life span than LED lamps.
3. The spectrum of visible light from sodium lamps is almost monochromatic while LED lamps offer significant colour advantages in street lighting.
