The ans to part c is current does not changebut if rail is moving away emf will increase into the page and nowcurrent should flow anticlockwise to produce B upward but thisdirection is opposite of other current than my question is whydirection does not change explain please will rate life saver !

(a) the induced emf is given by = B l v = ....... V I = / R = ....... A (b) the horizontal force will be FB = I l B = .......N (c) as the magnetic flux B.A is in effectdecreasing, the induced current flow through R is from b to a pointb is at higher potential (d) no, magnetic flux will increase through a loopto the left of ab here counter clockwise current will flow toproduce magnetic field the current in R is still from b to a
