alleryWhy do magnetic field lines never intersect each other?
ADistance would not be uniform
BDensity would not be uniform
CDiagram would not be updated
DDirection would not be unique
Answer & Solution
Correct answer: D. Direction would not be unique
1. A field line shows the direction of the field at each point.
2. Two lines crossing would give two directions at one point.
3. If they intersected, the direction of the magnetic field would not be unique.
4. So field lines do not intersect.
