Question

Magnetic field lines have a property that lines are ________________.

Options

A
Non intersecting
B
Intersect near south pole
C
Intersect near north pole
D
Intersect everywhere

Explanation

The magnetic field lines do not intersect, under normal conditions, without any external influences.

This option suggests that magnetic field lines do not intersect each other. In reality, magnetic field lines do not intersect because they represent the path of the magnetic field around a magnetic object. Magnetic field lines always form closed loops, and they do not cross each other.

This option suggests that magnetic field lines intersect near the south pole of a magnet. However, this is not correct. Magnetic field lines emerge from the north pole of a magnet and re-enter at the south pole, forming closed loops. They do not intersect each other at the south pole or anywhere else.

This option suggests that magnetic field lines intersect near the north pole of a magnet. Similar to option (b), this is not correct. Magnetic field lines do not intersect each other at the north pole or anywhere else. Instead, they emerge from the north pole and re-enter at the south pole.

This option suggests that magnetic field lines intersect at every point around a magnet. However, this is not correct. Magnetic field lines never intersect each other. They always form closed loops, and they do not cross.
