Question: A current-carrying conductor experiences a force in a magnetic field. What is the direction of this force given by Fleming\'s left-hand rule? (2020)

Options:

  1. Parallel to the field
  2. Opposite to the field
  3. Perpendicular to the field
  4. In the direction of current

Correct Answer: Perpendicular to the field

Exam Year: 2020

Solution: 

According to Fleming\'s left-hand rule, the force is perpendicular to both the magnetic field and the direction of current.

  4. In the direction of current

Questions & Step-by-Step Solutions

A current-carrying conductor experiences a force in a magnetic field. What is the direction of this force given by Fleming's left-hand rule? (2020)
  • Step 1: Identify the three components involved: the direction of the current, the direction of the magnetic field, and the direction of the force.
  • Step 2: Use your left hand to apply Fleming's left-hand rule. Point your thumb in the direction of the force (which you want to find).
  • Step 3: Point your first finger in the direction of the magnetic field (from north to south).
  • Step 4: Point your second finger in the direction of the current (from positive to negative).
  • Step 5: The direction your thumb points is the direction of the force experienced by the conductor.
  • Fleming's Left-Hand Rule – A rule used to determine the direction of force experienced by a current-carrying conductor in a magnetic field, where the thumb represents the force, the index finger represents the magnetic field direction, and the middle finger represents the current direction.
  • Magnetic Force on a Conductor – The principle that a conductor carrying an electric current will experience a force when placed in a magnetic field, with the direction of the force being determined by the orientation of the current and the magnetic field.
