The magnitude of the earth?s magnetic field at a place is \[{{B}_{0}}\] and the angle of dip is \[\delta \]. A horizontal conductor of length l lying along the magnetic north-south moves eastwards with a velocity v. The emf induced across the conductor is [Kerala PET 2005]

• A.            Zero                                         
• B.            \[{{B}_{0}}l\,v\sin \delta \]
• C.            \[{{B}_{0}}l\,v\]                  
• D.            \[{{B}_{0}}l\,v\cos \delta \]
