Question

The incorrect statement regarding the lines of force of the magnetic field B is:

• A. magnetic intensity is a measure of lines of force passing through unit area held normal to it.
• B. magnetic lines of force form a closed curve.
• C. inside a magnet, its magnetic lines of force move from the north pole of a magnet towards its south pole.
• D. magnetic lines of force never cut each other.

Answer 1

Answer: (C)

$\to$ Magnetic intensity is proportional to the number of magnetic field lines.
$\to$ Magnetic field lines of forces are closed curves.
$\to$ Inside the magnet, field lines move from the South Pole to the North Pole.
$\to$ Magnetic lines of force never cut each other.

Therefore, option C is incorrect
