Question

why magnetic field lines cross each other ? Draw the magnetic field lines (including
field directions) of the magnetic field due to a long straight solenoid. What important propert
of this field is indicated br this field line pattern ? Name any tivo factors on which the
magnitude of the magnetic field due to tlus solenoid depends.​

Answer 1

Answer:

THE two magnetic field lines can never intersect each other because two tangents can be drawn from that point of intersection which will give two directions of the field from the same point,which is impossible.So, the two magnetic field lines can never intersect each other.

The pattern of the magnetic field lines around a current-carrying solenoid is illustrated in Fig.1. ... The field lines inside the solenoid are in the form of parallel straight lines. This indicates that the magnetic field is the same at all points inside the solenoid. That is, the field is uniform inside the solenoid.
