Question

one conducting U- tube can slide into another U- tube,
maintaining electrical contacts between them a magnetic feild B is
acting perpendicular to the plane of the slide if each tube moves
at a constant speed v towards each other, then the EMF included in
circuit is ????

Blv are produced Both the emfs tend to send current in the same
direction, so they are added up |dϕdt|=2BlvRelative speed of
one tube with respect to other =2v
