A conductor is moved in a varying magnetic field. Name the law which determines
A conductor is moved in a varying magnetic field. Name the law which determines the direction of current induced in the conductor:
- A. Fleming's right hand rule
- B. Mohr's right hand rule
- C. Fleming's left hand rule
- D. Mohr's left hand rule
Step-by-step solution
When a conductor is moved in a magnetic field, an emf is induced. Fleming's right hand rule gives the direction of induced current: the thumb points in the direction of motion, index finger in the magnetic field direction, and middle finger gives induced current direction. This rule is specifically for generators, while Fleming's left hand rule is for motors. Therefore, option A is correct.
