Question

The direction of the force on a current carrying conductor held perpendicular to an uniform magnetic field is given by:

• A. Fleming's right hand rule
• B. Ampere's swimming rule
• C. Maxwell's right hand cork screw rule
• D. Fleming's left hand rule

Answer 1

Answer: (D)

Fleming's left hand rule

The direction of force (motion) of a current carrying conductor in a magnetic field is given by Fleming’s left hand rule.

It states that ‘ If we hold the thumb, fore finger and middle finger of the left hand perpendicular to each other such that the fore finger points in the direction of magnetic field, the middle finger points in the direction of current, then the thumb shows the direction of force (motion) of the conductor.
