Question

Consider the following statement:

The magnetic field of a magnet comes out of the north pole and goes into the south pole"
Based on what you know the divergence and curl of the magnetic and auxiliary fields why is this statement imprecise? Explain as fully as you can.

Answer 1

Because the Magnetic Field lines are closed- we need to express, which area of the space is considered for the given direction

Step-by-step explanation:

The magnetic field lines have enclosed nature- they do look like a circle. Once we consider a permanent magnet with the north and south pole, in the area outside from the magnet, lines go from the North towards the South pole, where they enter the magnet. However, inside the magnet, these lines have direction from the south to the north pole to close the ends of the line. So, once we consider the directions of the magnetic field inside the magnet, the given statement is not correct.
