Question:
An armature coil of an AC generator when moved in the magnetic field, induced current is produced.
a)Which is the law that helps to find the direction of current?
b)As per the law what does the fore finger represent?
Solution:
A generator is a device which converts mechanical energy into electrical energy. The law of Fleming's Right Hand Rule is used to determine the direction of current. The law states that if the fore finger, thumb and the middle finger are kept in a condition in which they are mutually perpendicular, then the fore finger represents the direction of magnetic field, thumb represents the direction of motion, and middle finger represents the direction of current.
Direct Answer:
(a) Fleming's Right Hand Rule
(b) Direction of magnetic field
