Question

Select the incorrect statement-:

Magnetic field lines are closed curves

No two field line can cross each other

Field lines can cross each other

The relative strength of the magnetic field is show by degree of closeness of the field lines

​

Answer 1

Answer:

i think the answer is option a

Answer 2

The incorrect statement is: Field lines can cross each other. (option c)

A magnetic field line is drawn tangential at a point. Therefore at any point, the tangent to the magnetic field line gives the direction of the magnetic field at that particular point. Magnetic field lines have various properties.

Properties of field lines:

• Field lines can never intersect each other. This means that field lines can never cross each other because two tangents at any point can never meet.
• The more close the field lines, the higher would be the intensity of the magnetic field.
• The magnetic field line is a vector quantity.
• The magnetic field lines start from the south pole and terminate at the north pole.
• The field lines form a closed loop.
• The magnetic field is stronger at the poles as the field lines become denser near the poles.
