What effect would you see if a wire was moved parallel to magnetic field lines?

Question

anonymous · Answer

I think you will see no effect because magnetic field acts on a wire only when the angle between magnetic field vector B and the wire is not zero or in general  Pi*n where n = 0,1,2,...

anonymous · Answer

agreed.... laurentz force will be generated only on perpendicular to the magnetic field....

anonymous · Answer

But I don't agree)
Lorentz's force will act on a wire at any angle except Pi*n.

anonymous · Answer

F $$= q \left( v \times B \right)$$ $$= I \left( L \times B \right)$$

anonymous · Answer

u sud agree ;)

anonymous · Answer

F = q v*B Sin Alpha 
Where alpha is the angle between vectors v and B.

anonymous · Answer

yes.... and alpha decides wht the angel is... right? alpha gives zero on pi*n....

anonymous · Answer

$$\sin \alpha $$ .. sorry

anonymous · Answer

Yes right, but I said that Lorentz force exists at any angle EXCEPT Pi*n.
