Magnetic lines of force due to a bar magnet do not intersect because
- A
A point always has a single net magnetic field
- B
The lines have similar charges and so repel each other
- C
The lines always diverge from a single point
- D
The lines need magnetic lenses to be made to intersect

$(c)$ Must every magnetic configuration have a north pole and a south pole? What about the field due to a toroid?
$(d)$ Two identical looking iron bars $A$ and $B$ are given, one of which is definitely known to be magnetised. (We do not know which one.) How would one ascertain whether or not both are magnetised? If only one is magnetised, how does one ascertain which one? [Use nothing else but the bars $A$ and $B$.]
