Two coils (X) and (Y), the area of coil (X) is double of that of coil (Y) while the number of turns of (X) is 1/3 of that of coil (Y). When the two coils are placed inside a magnetic field (its flux density (B) can be changed) where the coils’ planes are perpendicular to the flux lines direction and changing the flux density that affects the two coils by same rate then, the ratio between: “The average induced e.m.f in the coil (X)” /”The average induced e.m.f in the coil (Y)” =……..
(a) 1/6 (b) 3/4
(c) 2/3 (d) 2/5
