Question

Which of the following is not the property of magnetic lines of force? (CO 102.2)​

Answer 1

Answer:

Correct option is D)

Explanation:

Properties of magnetic lines of force are:

The imaginary lines which represent the direction of magnetic field, are known as magnetic lines of force. Magnetic lines of force are closed curves. Outside the magnet their direction is from north pole to south pole and inside the magnet these are from south to north pole. They neither have origin nor end. These lines do not intersect, because if they do so then it would mean two value of magnetic field at a single point, which is not possible. At the poles of the magnet the magnetic field is stronger because the lines of force there are crowded together and away from the poles the magnetic field is weak.

Answer 2

Answer:

The property of magnetic lines of force is Friction

Explanation:

From the above question,

Magnetic field lines do not form closed loops.

Magnetic lines of force are imaginary lines that represent the direction of the magnetic field. They are closed curves, and their direction outside the magnet is from the north pole to the south pole, and from the south pole to the north pole inside the magnet.

They have neither an origin nor an end, and never intersect, as this would mean two values of magnetic field at one point, which is impossible. The strength of the magnetic field is greatest at the poles of the magnet, where the lines of force are most crowded together, and weakest away from the poles.

Magnetic lines of force are imaginary lines which represent the direction of the magnetic field. These lines are closed curves, flowing from the north pole to the south pole outside the magnet and from south to north pole inside the magnet. They have no beginning or end, and never intersect as this would mean two values of the magnetic field at a single point. The magnetic field is strongest around the poles of the magnet, as the lines of force are crowded together, and weakest away from the poles.
