alleryTwo magnetic field lines can never cross because a compass would then point:
AIn two directions
BIn no direction
CIn one direction
DIn wide circles
Answer & Solution
Correct answer: A. In two directions
1. No two field lines are found to cross each other.
2. If they did, at the point of intersection the compass needle would point in two directions.
3. That is not possible, so the lines cannot cross.
