Question

Which rule is applied to find the direction of force acting on a current carrying wire, placed in a magnetic field?

• A. Fleming's right hand rule
• B. Fleming's left hand rule
• C. Right hand thumb rule
• D. Lenz Law

Answer 1

The correct option is B Fleming's left hand rule

Fleming's left hand rule is used to find the direction of force acting on a current carrying conductor, placed in a magnetic field. According the the Fleming's left hand rule, when we place the thumb, the index finger and the middle finger mutually perpendicular to each other such that the middle finger points to the direction of flow of current and the index finger points to the direction of magnetic field then the thumb points to the direction of force acting on the conductor.
