Model Answer
(i) If two magnetic field lines intersected, the compass needle at that point would point in two different directions simultaneously, which is not possible. Hence, magnetic field lines never intersect.
(ii) A uniform magnetic field is represented by equally spaced, parallel straight lines.

(Parallel, equally-spaced lines with arrows in the same direction)

Explanation
- For (i), the key reason is: at the point of intersection, the field would have two directions, which is physically impossible — examiners expect this specific logic.
- For (ii), "uniform field = equal spacing + parallel lines" is the complete answer. Drawing the diagram (even a rough one with arrows) is essential since the question asks for it. Unequal spacing would imply a non-uniform field.
