Question

the difference in the number of magnetic field lines entering and leaving a bar magnet is always ---------​

Answer 1

Answer:

The contribution to magnetic flux for a given area is equal to the area times the component of magnetic field perpendicular to the area. For a closed surface the number of magnetic field lines entering the surface is equal to the number of field lines exiting it. Thus the sum of magnetic flux is always equal to zero.

The contribution to magnetic flux for a given area is equal to the area times the component of magnetic field perpendicular to the area. For a closed surface the number of magnetic field lines entering the surface is equal to the number of field lines exiting it. Thus the sum of magnetic flux is always equal to zero.
