Magnetic field lines represent the direction and strength of a magnetic field. They are continuous closed loops that never start or end. They never intersect, and the tangent at any point gives the field's direction. Outside a magnet, lines go from the north to the south pole. However, inside the magnet, the direction is from the south pole to the north pole to complete the loop. Therefore, the statement "Inside the magnet the lines go from north pole to south pole" is incorrect.

Final Answer: Inside the magnet the lines go from north pole to south pole of the magnet
