The incorrect statement regarding the lines offorce of the magnetic field B is(1) Magnetic intensity is a measure of lines offorce passing through unit area held normalto it(2) Magnetic lines of force form a close curve(3) Inside a magnet, its magnetic lines of forcemove from north pole of a magnet towardsits south pole(4) Due to a magnet, magnetic lines of forcenever cut each other
Solution
The incorrect statement regarding the lines of force of the magnetic field B is:
(1) Magnetic intensity is a measure of lines of force passing through unit area held normal to it. (2) Magnetic lines of force form a close curve. (3) Inside a magnet, its magnetic lines of force move from the north pole of a magnet towards its south pole. (4) Due to a magnet, magnetic lines of force never cut each other.
To identify the incorrect statement, we will analyze each option:
(1) Magnetic intensity is a measure of lines of force passing through unit area held normal to it. This statement is correct. Magnetic intensity is indeed a measure of the number of magnetic field lines passing through a unit area held normal to it. Therefore, this is not the incorrect statement.
(2) Magnetic lines of force form a close curve. This statement is also correct. Magnetic field lines always form closed loops, meaning they start from the north pole of a magnet, curve around, and end at the south pole. Therefore, this is not the incorrect statement.
(3) Inside a magnet, its magnetic lines of force move from the north pole of a magnet towards its south pole. This statement is incorrect. Inside a magnet, the magnetic field lines actually move from the south pole to the north pole. Therefore, this is the incorrect statement.
(4) Due to a magnet, magnetic lines of force never cut each other. This statement is correct. Magnetic field lines do not intersect or cut each other. They always repel each other, resulting in non-intersecting lines. Therefore, this is not the incorrect statement.
In conclusion, the incorrect statement regarding the lines of force of the magnetic field B is option (3) - Inside a magnet, its magnetic lines of force move from the north pole of a magnet towards its south pole.
