State the characteristics of magneticfield lines.

Answer»

Solution :(1) The magneticfieldlines emergyfrom north pole and merge at the southpole outsidethe magnet ,whileinsidethe magnet the directionof fieldlines is FROMITS south poleto itsnorth pole .
Thus , themagnetic fieldlines are closedand continuouscurve.
(2) The magnetic fieldlines are crowded near the polewhere the magnetic fieldis strongarefar APART near the middle of THEMAGNET and farfrom themagnetwhere the magneticfieldis weak .
(3) Themagnetic fieldlines never intersect each otherbecauseif they do so ,there wouldbe two directions ofmagneticfieldat thatpointwhichis absurd.
(4) In case the field lines are parallel and equidistance , theserepresent a UNIFROM magneticfield .
