Question

what are magnetic field lines? justify the following statement
a) two magnetic field lines never intersects each other
B) magnetic field are closed curves.​

Answer 1

Answer:

But if the two magnetic field lines intersect one another, then the resultant force on a North Pole placed at the point of intersection will be along to directions, which is not possible. (b) Magnetic field lines are closed curves or forms a closed loop. This is because two magnetic field lines can never intersect.

Answer 2

Answer:

• A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

a) The two magnetic field lines do not intersect each other because if they do it means at the point of intersecting the compass needle is showing two different directions which are not possible.

b) Magnetic field lines are closed curve because magnetic monopoles do not exit. Outside a magnet direction of magnetic field, lines are from north to the South Pole and inside a magnet the direction if from south to north, hence forming a closed loop.
