niassu said:in page 218 generators i dont understand hoew when the coil is vertical it cuts no magentic field ???
because when it becomes vertical..the direction of movement is parallel to the direction of magnetic field..hence no current is induced!!
Use Fleming's right hand rule..to understand this..u'll notice it urself
as u already know that the current and the direction of force shud be perpendicular..!! just try doing it..
if u still dont understand..let me know...i'll try to post some pics..to help u understand

niassu said:i would be pleased to see ur pics sorry for making u tired but "Jazak Allah Kairan" hope that god bless u for help
i m sorry but i have many other doubts too can i post next time or are u busy?????
