Fleming's right-hand rule gives the direction of the induced current. In this rule, the thumb points along the direction of:
AMotion of the conductor
BMagnetic field
CInduced current
DForce on the conductor
Answer & Solution
Correct answer: A. Motion of the conductor
1. Fleming's right-hand rule applies to a conductor moving in a magnetic field that induces a current.
2. The chapter assigns: thumb to the direction of motion of the conductor, index finger to the magnetic field, and middle finger to the induced current.
3. The option the induced current is given by the middle finger, not the thumb, so it is wrong.
