if the direction of the current keeps changing ( ac), then the direction of the magnetic field keeps changing with the same frequency! .. thats all i know :P
anonymous
  • anonymous
but then how do we draw it?
anonymous
  • anonymous
you can't draw it.. these fields are a function of time.. are you asking me a graph of field vs time?

nope the paterns? of field lines
anonymous
  • anonymous
yea well .. at every instant they would keep changing.. !! you ll have to introduce time axis somehow? :-/.. ishaan is much better .. he ll come up with something now :D

oh.thnks and lets see what he brings out :P

hmm can't we use right hand thumb rule |dw:1327825525015:dw||dw:1327825574961:dw|I think the direction changes right? i mean in AC current the direction of current changes with every cycle.

  • anonymous
yeah then how do we show it in a solenoid, both the direction?
anonymous
  • anonymous
lt hand rule only right?
anonymous
  • anonymous
solenoid hmm lemme think |dw:1327825727114:dw|i am only using right hand thumb rule

Yea but.. she wants to show the pattern of magnetic fields.. and besides . isn't that just the cross section??? . thushanth, you want only crossesctional view or the whole solenoid?
anonymous
  • anonymous
whole soloneid..
anonymous
  • anonymous
okies there is a magnetic field outside and inside the solenoid
anonymous
  • anonymous
what you want
anonymous
  • anonymous
the pattern, show it in the solenoid..
anonymous
  • anonymous
the magnetic force is strong inside the solenoid only so you can ignore the other lines of magnetic force. and due to ac current the magnetic force will changes it's direction
anonymous
  • anonymous
its* not it's
anonymous
  • anonymous
so v r nt able to show the pattern?

i copioed
anonymous
  • anonymous
yeah math3v4 exactly like that but thushanth the direction will change every cycle
anonymous
  • anonymous
oh, so v r nt able to show the chnge in direction right.
anonymous
  • anonymous
no there is no one particular direction you will have to show both of the directions
anonymous
  • anonymous
drw two diagrams.?
