11Look at the videos i provided in
http://targetiit.com/iit_jee_forum/posts/must_watch_3047.html
The first two provide experimental proof that magnetic field is non-conservative!!!
9kaymant sir
if a q comes in jee 09
shud we take it as conservative or non conservative ?
66Have a look here:
http://en.wikipedia.org/wiki/Conservative_force
By the way, there is a potential defined for magnetic fields as well. (The only trouble is that this is a vector potential.)
9ok got it as EM consist of electric vector also it doent form close loop i guess
33Electromagnetic.. hmm... [12]
Both electric and magnetic... combined....
pata nahi... :(
6no its not! as there is no term as magnetic potential energy which stands only for conservative forces!!!!!!!!!!!!!
cheers!!!!!!!!!
11celestine yeh dekh
hope it will make it crystal clear

9yes magnetic i agree ( nice pic manipal [1])
im asking for electromagnetic . it comes in a matrix match in bmat and ans key
doesnt match these two
9another one help needed
are electromagnetic lines of force always closed or open ?
9remember that work done by mag force is 0 always ie independent of path
33But why PE is defined for magnetic moment in unform magnetic field...
PE=-M.B
1yes ..........i knw the answer but the way u asked the question i got confused...
11but ur ques should not be like this
it should have been more clear
yaar tu to phasane ke liye ques pooch raha tha( u were trying to fall us in a trap)
9this i learnt from Bmat home test i think it must be right only
9ans is no !!!
its non conservative force as its direction is always perpendicular to velocity hence depends on state of motion of body ( like friction always opp to vel of body )
the irony here is that however WD =0
