## In an a.c generator, coil of N turns and area A is rotated at V revolutions per second in a uniform magnetic field B.Write the expression for the emf produced. A 100-turn coil of area 0.1 m2 rotates at half a revolution per second. It is placed in a magnetic field 0.01 T perpendicular to the axis of rotation of the coil. Calculate the maximum voltage generated in the coil.
