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 . |
