Question

How does one use the right hand rule to determine the direction of the force applied to a current carrying wire?

• A. Point the fingers of the right hand in the same direction as the magnetic lines of force
• B. Point the thumb at right angles to the lines of force
• C. Point the fingers of the right hand along the wire in the direction of the current
• D. Point the thumb in the direction of the magnetic lines of force
• E. Point the fingers of the right hand against the direction of the magnetic lines of force

Answer 1

The correct option is A Point the fingers of the right hand in the same direction as the magnetic lines of force

Right hand palm rule states if we stretch our right hand such that thumb and rest of the fingers are mutually perpendicular , and fingers show the direction of magnetic field lines , thumb shows the direction of current then a perpendicular on the palm will show the direction of force on current carrying wire .
