Question

what are magnetic field lines? give their important properties​

Answer 1

Explanation:

1) A magnetic field lines is an imaginary curve along which a free unit north pole tends to move. 3) The tangent to the magnetic field lines at any point gives the direction of magnetic field at that point. 4) Two magnetic field lines never intersect each other. 5) It is vector quantity.

Answer 2

Answer:

Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:

-The field is tangent to the magnetic field line.

-Field strength is proportional to the line density.

Field lines cannot cross.

-Field lines are continuous loops.
