State whether the following statement are true of false giving reason

1.	State whether the following statement are true of false giving reason in brif : (a) The dimension of `(h//e)` is the same as that of magnetic flux `phi`. (b) The dimensions of electric and magnetic flux are same. (c ) A coil or a metal wire is kept stationary in a non-uniform magnetic field. An e.m.f. is induced in the coil. (d) An e.m.f. can be induced between the two ends of a straingth copper wire when it is moved through a magnetic field.
Answer» (a) True. `(h)/(e) = ("joule - sec")/("coulomb") = ("joule")/("ampere")` = magnetic flux (b) False, for reason, see text. (c ) False, As magnetic flux does not change with time. (d) True, as `e = B upsilon l sin theta`.
