Question

In Fleming's right hand rule middle finger indicates the direction of

• A. Magnetic field
• B. Induced electric current
• C. Mechanical energy
• D. Motion of the conductor

Answer 1

The correct option is B Induced electric current

Fleming's right-hand rule gives which direction the current flows.
According to the rule, right hand is held with the thumb, first finger and second finger mutually perpendicular to each other.
According to the figure, the thumb is pointed in the direction of motion of the conductor. If the first finger is pointed in the direction of the magnetic field. (north to south) then the second finger represents the direction of the induced or generated current (the direction of the induced current will be the direction of conventional current; from positive to negative).
