In the Left-Hand Rule for Conductors, the encircling fingers point in the direction of the ?

• A. Current
• B. Magnetic field
• C. Resistance
• D. Voltage

Answer: (B)

Fleming’s Left-Hand Rule helps you determine the direction of the force on a current-carrying conductor in a magnetic field. The encircling (fingers) part points along the magnetic field direction, which forms circular lines around a current-carrying wire. The middle finger shows the current direction, and the thumb points in the direction of the force (the motion) on the conductor. Because magnetic field lines wrap around the wire, those circling fingers align with the magnetic field, making magnetic field the correct description of what the encircling fingers indicate.
