The expression for the emf produced by A. C. generator is?
Correct answer: A. NωAB Sinθ
- A. NωAB Sinθ
- B. NωAB Cosθ
- C. NωAB
- D. ILB Cosθ
Explanation
The correct statement is A. NωAB Sinθ. This expression represents the emf produced by an AC generator when the coil is rotated in a magnetic field with an angle θ between the field and the coil's plane.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
