what do you mean by magnetic field lines of a bar magnet ?
Answers
Answer:
Magnetic field lines inside the magetic field are the imaginary lines along which a hypothetical north pole moves
Magnetic fleld lines show the direction of the magnetic field, the arrow indicates which direction.
Outside magnet: from north to south pole Inside magnet: from south to north pole
The amount of field lines tell you about the strength of the field at that point.
When all the field lines are equidistant the field is uniform (of same strength).
Properties of magnetic field lines:
Magnetic field lines moves from north to south pole outside the magnet and south to north pole inside the magnet.
Two magnetic field lines can never intersect each other because at their point of intersection there will be two directions at a time which is impossible.
If a tangent is drawn at any point on magnetic field line then it gives the direction of magnetic field at that point.
Answer:Magnetic field around the bar magnet is the region in which magnetic force due to the bar magnet can be experienced. Magnetic field lines start from the north pole and terminates at the south pole outside the magnet.
