Question

Which of the following rules is used to determine the force on a current carrying conductor kept inside a magnetic field?

• A. Maxwell's corkscrew rule
• B. Fleming's left-hand rule
• C. Right hand thumb rule
• D. Fleming's right-hand rule

Answer 1

Answer:

B. Fleming's left-hand rule

• Fleming's left-hand rule is used to find the direction of force on a current-carrying conductor placed within a magnetic field.

• According to Fleming's Left-Hand Rule: -

• Stretch the thumb, forefinger, and middle finger of your left hand so that they are mutually perpendicular.

• The forefinger represents the direction of the magnetic field.

• The middle finger represents the direction of the current.

• The thumb represents the direction of the force (or motion) on the conductor.
