(a) Two magnetic field lines do not intersect each other. Why?
(b) How is a uniform magnetic field in a given region represented? Draw a diagram in support of your answer
Answer
(a) Two magnetic field lines never intersect each other because if they did, it would mean that at the point of intersection, the magnetic field has two different directions — one along each line but the magnetic field at any given point can have only one unique direction. Therefore, magnetic field lines do not cross each other.
(b) A uniform magnetic field means that the magnitude and direction of the magnetic field are the same at all points in the region.
It is represented by parallel, equally spaced straight lines as shown in below figure :
