here are the diagrams... although they aren't drawn perfectly...
If you need explanations let me know

 

[WellWIshER]

i doubt ur nov 05 graph

i think da second part should pe positive and da other should be negative

THHHHHHHHHHHHHHAAAAAAAAAAAAAAAAAAANNNNNNNNNNNNNNNNNNNKKKKKKKKKKKSSSSSSSSSSSSSS ALOT!!!!!!!!!!!!
yes plz explain may 07 ques

@well wisher
do keep in mind the negative sign in emf and magnetic flux equation!!!

 

[WellWIshER]

omg!!! thanx 4 pointing tht out

 

[intel1993]

hey i also think the same as wellwisher thinks in nov 05 that 2nd part shud be positive n 3rd part aS NEG................
PLZZZZ EXPLAIN

PLZZZZ EXPLAIN

da thng here is dude tht emf is negative theta/time

so negative negative will give positive......

and vice versa!!

 

[bluebeads98]

could you explain the magnetic filed/emf graphh part by partt?

 

[skyfox]

anyone can explain how to draw a graph on may june 2005 q5b ? please.... T_T

 

[beacon_of_light]

also explain j02 q6 a

hope you understand that

 

[alevel4a]

also explain j02 q6 a

hope you understand that

why the graph is like is?????

 

[beacon_of_light]

As the gradient goes from max to zero , voltage would go from max to zero ...

and when the current decreases(decreasing constant gradient)... V would be constant but positive this time due to the negative sign in magnetic flux and emf equation...
