what is the characteristics of field lines ?
Answers
The properties of magnetic field lines can be summarized by these rules: The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. The strength of the field is proportional to the closeness of the lines.
Answer
A magnetic force experienced around the region of a magnet is called magnetic field. The characteristics of magnetic field lines are as follows:
(i) The magnetic field lines of a magnet start from the North Pole(N) and reach the South Pole(S) and these lines are in the north-south direction inside the magnet.
(ii) The region in which the field lines are at close distance to each other has a strong magnetic field and if the field lines are at far distance from each other, the region has a weak magnetic field. Near the poles of a magnet, the field lines are at close distance from each other so there is strong magnetic field.
(iii) The magnetic field is a very vector quantity. So it has magnitude and direction both. The tangent is drawn at any point of a magnetic field line.
(iv) Magnetic field lines do not intersect each other.
