Question

The direction of the force acting on a current-carrying conductor placed perpendicular to a magnetic field is given by Flemings' left-hand rule.

• A. True
• B. False

Answer 1

The correct option is A True

1. When a current-carrying conductor is placed in a magnetic field, it experiences a force,
2. The direction of force acting on a current-carrying conductor placed perpendicular to the magnetic field is given by Flemings's left-hand rule.
3. As per this rule if we arrange our thumb, forefinger, and middle finger of the left-hand perpendicular to each other, then the thumb points towards the direction of the force experienced by the conductor, and the forefinger points towards the direction of the magnetic field, and the middle finger points towards the direction of the electric current.

Thus the given statement is true.
