Magnetic field lines of two magnets are shown in fig. A and fig. B. Select the figure that represents the correct pattern of field lines. Give reasons for your answer. Also, name the poles of the magnets facing each other.

R.E.F image  

Solution : In the given figure A & B 

The figure B is the correct 

Pattern of field lines.

Reason : Magnetic lines of forces never 

intersect to each other 

(it is the propertiys of magnetic 

lines of forces)

So, the figure A is is not correct
