Two magnetic field lines never cross because at the crossing point
Afield direction would be unclear
Bthe field would become zero
Cthe lines would carry charge
Dthe lines would close up
Answer & Solution
Correct answer: A. field direction would be unclear
The tangent to a field line gives the direction of B, so a crossing would give two directions at one point.
